">Debian Edu, also known as
26 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
27 out-of-the box environment of a completely configured school
28 network. Immediately after installation a school server running all
29 services needed for a school network is set up just waiting for users
30 and machines being added via GOsa², a comfortable Web-UI. A netbooting
31 environment is prepared using PXE, so after initial installation of
32 the main server from CD, DVD or USB stick all other machines can be
33 installed via the network. The provided school server provides LDAP
34 database and Kerberos authentication service, centralized home
35 directories, DHCP server, web proxy and many other services. The
37 <a href=
"http://people.skolelinux.org/pere/blog/Educational_applications_included_in_Debian_Edu___Skolelinux__the_screenshot_collection____.html
">more
38 than
60 educational software packages
</a
> and more are available from
39 the Debian archive, and schools can choose between KDE, Gnome, LXDE
40 and Xfce desktop environment.
</p
>
42 <p
>This is the fifth test release based on Debian Wheezy. Basically
43 this is an updated and slightly improved version compared to the
44 Squeeze release.
</p
>
46 <p
>ALERT: Alpha based installations should reinstall or downgrade the
47 versions of gosa and libpam-mklocaluser to the ones used in this beta
50 <p
><strong
>Software updates
</strong
></p
>
54 <li
>Switched roaming workstation profiles from wicd to network-manager
55 for network configuration, as wicd didn
't work any more.
</li
>
56 <li
>Changed version numbers of patched gosa and libpam-mklocaluser
57 packages to make sure our locally patched versions will be replaced
58 by the official packages when they are released from Debian. Those
59 installing alpha version need to reinstall or manually downgrade gosa
60 and libpam-mklocaluser.
</li
>
61 <li
>Added bluetooth tools to the default desktop (bluedevil, blueman).
</li
>
62 <li
>Added tools for sharing the desktop on KDE (krdc, krfb).
</li
>
63 <li
>Added valgrind to the default installation for easier debugging of
64 crash bugs.
</li
>
68 <p
><strong
>Other changes
</strong
></p
>
72 <li
>Fixed artwork package to work with gnome, no longer break
73 desktop=gnome installations.
</li
>
74 <li
>Adjusted installer to now work when forced to use a proxy with the
75 netinst CD.
</li
>
76 <li
>Fixed code detecting and setting/loading hardware specific
77 setup/firmware to work more robust out of the box.
</li
>
78 <li
>Adjusted Kerberos setup to detect realm and server settings at
79 install time instead of dynamically at run time. This avoid a crash
80 with krb5-auth-dialog on diskless workstations without a DNS name.
</li
>
81 <li
>Worked around misfeature in network-manager not calling the dhclient
82 exit hooks, causing automatic proxy configuration and automatic host
83 name setting at run time to work again.
</li
>
84 <li
>Fixed feature setting the default Iceweasel start page from URL
85 fetched from LDAP, to allow schools to set the global default by
86 updating the dc=skole,dc=skolelinux,dc=no LDAP object.
</li
>
87 <li
>Changed default host name on all networked machines to be unique
88 (generated from MAC or reverse DNS) after boot.
</li
>
89 <li
>Adjusted partition sizes to make sure they are big enough.
</li
>
93 <p
><strong
>Known issues
</strong
></p
>
97 <li
>Grub is missing the new artwork.
</li
>
98 <li
>KDE fail to understand the wpad.dat file provided, causing it to
99 not use the http proxy as it should.
</li
>
100 <li
>Chromium also fail to use the proxy.

201 <li

</li

202 <li
>Dropped menu-xdg from the KDE desktop option, to drop the Debian
203 submenu. It was not included with Gnome, LXDE or Xfce, so this
204 brings KDE in line with the others.
</li
>
205 <li
>Dropped xdrawchem, xjig and xsok from our default installation as
206 they don
't have a desktop menu entry and thus won
't show up in the
207 menu now that menu-xdg was removed.

210 X display was in use and killed the processes of the active users

226 debconf database after installation on Main Server installations.

227 <li

>In the
<a href=
"http://www.skolelinux.org/
">Debian Edu /
278 Skolelinux
</a
> project, we include a post-installation test suite,
279 which check that services are running, working, and return the
280 expected results. It runs automatically just after the first boot on
281 test installations (using test ISOs), but not on production
282 installations (using non-test ISOs). It test that the LDAP service is
283 operating, Kerberos is responding, DNS is replying, file systems are
284 online resizable, etc, etc. And it check that the PXE service is
285 configured, which is the topic of this post.
</p
>
287 <p
>The last week I
've fixed the DVD and USB stick ISOs for our Debian
288 Edu Wheezy release. These ISOs are supposed to be able to install a
289 complete system without any Internet connection, but for that to
290 happen all the needed packages need to be on them. Thanks to our test
291 suite, I discovered that we had forgotten to adjust our PXE setup to
292 cope with the new names and paths used by the netboot d-i packages.
293 When Internet connectivity was available, the installer fall back to
294 using wget to fetch d-i boot images, but when offline it require
295 working packages to get it working. And the packages changed name
296 from debian-installer-
6.0-netboot-$arch to
297 debian-installer-
7.0-netboot-$arch, we no longer pulled in the
298 packages during installation. Without our test suite, I suspect we
299 would never have discovered this before release. Now it is fixed
300 right after we got the ISOs operational.
</p
>
302 <p
>Another by-product of the test suite is that we can ask system
303 administrators with problems getting Debian Edu to work, to run the
304 test suite using
<tt
>/usr/sbin/debian-edu-test-install
</tt
> and see if
305 any errors are detected. This usually pinpoint the subsystem causing
306 the problem.

326 #debian-edu

331 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p

333 <p
>I
'm a
25 year old free software enthusiast, living in Romania,
334 which is also my country of origin. Back in
2009, at a New Year
's Eve
335 party, I had a very nice
<strike
>beer
</strike
> discussion with a
336 friend, when we realized we have no organised Debian community in our
337 country. A few days later, we put together the infrastructure for such
338 community and even gathered a nice Debian-ish crowd. Since then, I
339 began my quest as a free software hacker and activist and I am
340 constantly trying to cover as much ground as possible on that
343 <p
>A few years ago I founded a small web development company, which
344 provided me the flexible schedule I needed so much for my
345 activities. For the last
13 months, I have been the Technical Director
346 of
<a href=
"http://ceata.org/
">Fundația Ceata
</a
>, which is a free
347 software activist organisation endorsed by the FSF and the FSFE, and
348 the only one we have in our country.
</p
>
350 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
351 project?
</strong
></p
>
353 <p
>The idea of participating in the Debian Edu project was a surprise
354 even to me, since I never used it before I began getting involved in
355 it. This year I had a great opportunity to deliver a talk on
356 educational software, and I knew immediately where to look. It was a
357 love at first sight, since I was previously involved with some of the
358 technologies the project incorporates, and I rapidly found a lot of
359 ways to contribute.
</p
>
361 <p
>My first contributions consisted in translating the installer and
362 configuration dialogs, then I found some bugs to squash (I still
363 haven
't fixed them yet though), and I even got my eyes on some other
364 areas where I can prove myself helpful. Since the appetite for free
365 software in my country is pretty low, I
'll be happy to be the first
366 one around here advocating for the project
's adoption in educational
367 environments, and maybe even get my hands dirty in creating a flavour
368 for our own needs. I am not used to make very advanced plannings, so
369 from now on, time will tell what I
'll be doing next, but I think I
370 have a pretty consistent starting point.

375 <p
>Not a long time ago, I was in the position of configuring and
376 maintaining a LDAP server on some Debian derivative, and I must say it
377 took me a while. A long time ago, I was maintaining a bigger
378 Samba-powered infrastructure, and I must say I spent quite a lot of
379 time on it. I have similar stories about many of the services included
380 with Skolelinux, and the main advantage I see about it is the
381 out-of-the box availability of them, making it quite competitive when
382 it comes to managing a school
's network, for example.
</p

384 <p
>Of course, there is more to say about Skolelinux than the
385 availability of the software included, its flexibility in various
386 scenarios is something I can
't wait to experiment
"into the wild

387 only played with virtual machines so far). And I am sure there is a
388 lot more I haven
't discovered yet about it, being so new within the

394 <p
>As usual, when it comes to Debian Blends, I see as the biggest
395 disadvantage the lack of a numerous team dedicated to the
396 project. Every day I see the same names in the changelogs, and I have
397 a constantly fear of the bus factor in this story. I
'd like to see
398 Debian Edu advertised more as an entry point into the Debian
399 ecosystem, especially amongst newcomers and students. IMHO there are a
400 lot low-hanging fruits in terms of bug squashing, and enough
401 opportunities to get the feeling of the Debian Project
's dynamics. Not
402 to mention it
's a very fun blend to work on!

404 <p

405 with the main Debian release and documentation. This is common though

411 <p

415 <a href=

418 get through the night without headaches. Of course, there is much more
419 stuff in this bag, but I

424 <p

432 <li

436 <li

447 <p

>There is a certain cross-over between the
461 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
462 project
</a
> and
<a href=
"http://www.edubuntu.org/
">the Edubuntu
463 project
</a
>, and for example the LTSP packages in Debian are a joint
464 effort between the projects. One person with a foot in both camps is
465 Jonathan Carter, which I am now happy to present to you.
</p
>
467 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
469 <p
>I
'm a South-African free software geek who lives in Cape Town. My
470 days vary quite a bit since I
'm involved in too many things. As I
'm
471 getting older I
'm learning how to focus a bit more :)
</p
>
473 <p
>I
'm also an Edubuntu contributor and I love when there are
474 opportunities for the Edubuntu and Debian Edu projects to benefit from
475 each other.
</p
>
477 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
478 project?
</strong
></p
>
480 <p
>I
've been somewhat familiar with the project before, but I think my
481 first direct exposure to the project was when I met Petter
482 [Reinholdtsen] and Knut [Yrvin] at the Edubuntu summit in
2005 in
483 London. They provided great feedback that helped the bootstrapping of
484 Edubuntu. Back then Edubuntu (and even Ubuntu) was still very new and
485 it was great getting input from people who have been around longer. I
486 was also still very excitable and said yes to everything and to this
487 day I have a big todo list backlog that I
'm catching up with. I think
488 over the years the relationship between Edubuntu and Debian-Edu has
489 been gradually improving, although I think there
's a lot that we could
490 still improve on in terms of working together on packages. I
'm sure
491 we
'll get there one day.
</p
>
493 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
494 Edu?
</strong
></p
>
496 <p
>Debian itself already has so many advantages. I could go on about
497 it for pages, but in essence I love that it
's a very honest project
498 that puts its users first with no hidden agendas and also produces
499 very high quality work.
</p
>
501 <p
>I think the advantage of Debian Edu is that it makes many common
502 set-up tasks simpler so that administrators can get up and running
503 with a lot less effort and frustration. At the same time I think it
504 helps to standardise installations in schools so that it
's easier for
505 community members and commercial suppliers to support.
</p
>
507 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
508 Edu?
</strong
></p
>
510 <p
>I had to re-type this one a few times because I
'm trying to
511 separate
"disadvantages
" from
"areas that need improvement
" (which is
512 what I originally rambled on about)
</p
>
514 <p
>The biggest disadvantage I can think of is lack of manpower. The
515 project could do so much more if there were more good contributors. I
516 think some of the problems are external too. Free software and free
517 content in education is a no-brainer but it takes some time to catch
518 on. When you
've been working with the same proprietary eco-system for
519 years and have gotten used to it, it can be hard to adjust to some
520 concepts in the free software world. It would be nice if there were
521 more Debian Edu consultants across the world. I
'd love to be one
522 myself but I
'm already so over-committed that it
's just not possible
525 <p
>I think the best short-term solution to that large-scale problem is
526 for schools to be pro-active and share their experiences and grow
527 their skills in-house. I
'm often saddened to see how much money
528 educational institutions spend on
3rd party solutions that they don
't
529 have access to after the service has ended and they could
've gotten so
530 much more value otherwise by being more self-sustainable and
531 autonomous.
</p
>
533 <p
><strong
>Which free software do you use daily?
</strong
></p
>
535 <p
>My main laptop dual-boots between Debian and Windows
7. I was
536 Windows free for years but started dual-booting again last year for
537 some games which help me focus and relax (Starcraft II in
538 particular). Gaming support on Linux is improving in leaps and bounds
539 so I suppose I
'll soon be able to regain that disk space :)
</p
>
541 <p
>Besides that I rely on Icedove, Chromium, Terminator, Byobu, irssi,
542 git, Tomboy, KVM, VLC and LibreOffice. Recently I
've been torn on
543 which desktop environment I like and I
'm taking some refuge in Xfce
544 while I figure that out. I like tools that keep things simple. I enjoy
545 Python and shell scripting. I went to an Arduino workshop recently and
546 it was awesome seeing how easy and simple the IDE software was to get
547 up and running in Debian compared to the users running Windows and OS
550 <p
>I also use mc which some people frown upon slightly. I got used to
551 using Norton Commander in the early
90's and it stuck (I think the
552 people who sneer at it is just jealous that they don
't know how to use
555 <p
><strong
>Which strategy do you believe is the right one to use to
556 get schools to use free software?
</strong
></p
>
558 <p
>I think trying to force it is unproductive. I also think that in
559 many cases it
's appropriate for schools to use non-free systems and I
560 don
't think that there
's any particular moral or ethical problem with
563 <p
>I do think though that free software can already solve so so many
564 problems in educational institutions and it
's just a shame not taking
565 advantage of that.
</p
>
567 <p
>I also think that some curricula need serious review. For example,
568 some areas of the world rely heavily on very specific versions of MS
569 Office, teaching students to parrot menu items instead of learning the
570 general concepts. I think that
's very unproductive because firstly, MS
571 Office
's interface changes drastically every few years and on top of
572 that it also locks in a generation to a product that might not be the
573 best solution for them.
</p
>
575 <p
>To answer your question, I believe that the right strategy is to
576 educate and inform, giving someone the information they require to
577 make a decision that would work for them.

">Debian Edu, also known as
598 Skolelinux
</a
>, is a Linux distribution based on Debian providing an
599 out-of-the box environment of a completely configured school
600 network. Immediately after installation a school server running all
601 services needed for a school network is set up just waiting for users
602 and machines being added via GOsa², a comfortable Web-UI. A netbooting
603 environment is prepared using PXE, so after initial installation of
604 the main server from CD, DVD or USB stick all other machines can be
605 installed via the network. The provided school server provides LDAP
606 database and Kerberos authentication service, centralized home
607 directories, DHCP server, web proxy and many other services. The

>
794 <p
>I would add also the fact that it is based on the rock solid Debian
795 distribution, which ensures stability and provides a huge collection
796 of educational free software.
</p

798 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
799 Edu?
</strong
></p
>
801 <p
>Maybe the lack of manpower to do lobbying on the
802 project. Sometimes, people who need to take decisions concerning IT do
803 not have all the elements to evaluate properly free software
804 solutions. The fact that support by a company may be difficult to find
805 is probably a problem if the school does not have IT personnel.
</p
>
807 <p
>One can find support from a company by looking at
808 <a href=
"http://wiki.debian.org/DebianEdu/Help/ProfessionalHelp
">the
809 wiki dokumentation
</a
>, where some countries already have a number of
810 companies providing support for Debian Edu, like Germany or
811 Norway. This list is easy to find readily from the manual. However,
812 for other countries, like France, the list is empty. I guess that
813 consultants proposing support for Debian would be able to provide some
814 support for Debian Edu as well.
</p

816 <p
><strong
>Which free software do you use daily?
</strong
></p
>
818 <p
>I am using the KDE Plasma Desktop. But the pieces of software I use
819 most runs in a terminal: Mutt and OfflineIMAP for emails, latex for
820 scientific documents, mpd for music. VIM is my editor of choice. I am
821 also using the mathematical software
822 <a href=
"http://www.scilab.org/en/scilab/about
">Scilab
</a
> and
823 <a href=
"http://www.sagemath.org/index.html
">Sage
</a
> (built from
824 source as not completely packaged for Debian, yet).
826 <p
><strong
>Do you have any suggestions for teachers interested in
827 using the free software in Debian to teach mathematics and
828 statistics?
</strong
></p
>
830 <p
>I do not have any
"nice
" recommendations for statistics. At our
831 university, we use both
<a href=
"http://www.r-project.org/
">R
</a

832 Scilab to teach statistics and probabilistic simulations. For
833 geometry, there are nice programs:

855 <p

1029 <p
>Jeg heter Nirosan Thiyagalingam. Jeg er
24 år og studerer
1030 dataingeniør studiet ved Høgskolen i Sør Trøndelag. Interessen for
1031 data har siden ung alder vært tilstede og jeg har i tillegg alltid
1032 vært glad i å lære nye ting. Med teknologi som endres svært hurtig er
1033 det alltid noe nytt å lære. Noe som igjen har gjort det svært
1034 interessant å følge med på utviklingen. Jeg valgte dataingeniør
1035 studiet grunnet ønske om å lære enda mer om programmering og utvikling
1036 av store systemer.
</p
>
1038 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1040 <p
>Skolelinux prosjektet hørte jeg først om i media. Men det var først
1041 når jeg skulle velge bacheloroppgave at jeg fattet mer interesse for
1042 prosjektet. Et enkelt søk på nettet førte meg til skolelinux sine
1043 hjemmesider. Informasjonen jeg fant der gjorde meg enda nysgjerrig og
1044 jeg valgte derfor en oppgave som gikk ut på å få en
1045 <a href=
"http://www.raspberrypi.org
">Raspberry PI
</a
>. Altså en
1046 ultra-billig datamaskin til å kjøre Debian Edu på lik linje med
1047 vanlige datamaskiner. I løpet av prosjektet ble det gjort mye
1048 forskning på nettet. Det var mye jeg måtte forstå rundt hvordan
1049 operativsystemet Linux fungerte før jeg kunne angripe
1050 problemet. Prøvde først å finne ut hvordan man kunne transformere en
1051 vanlig installasjon av Skolelinux til Raspberry PI, men dette var
1052 altfor vanskelig å jeg endte opp med mer spørsmål enn svar. Det ble
1053 videre opprettet kontakt med Skolelinux utviklere på IRC der jeg fikk
1054 diskutert hvilken retning jeg burde gå for å få til en fullverdig
1055 løsning. Det ble bestemt at jeg skulle gå for å først installere
1056 <a href=
"http://www.raspbian.org/
">Raspian
</a
>. Dette er et
1057 operativsystem basert på Debian spesiallaget for Raspberry Pi sin
1058 maskinvare. Nå som Debian var installert på datamaskinen gjenstod det
1059 å installere de nødvendige Skolelinux pakkene for å få til et
1060 fullverdig system. Disse pakkene ble installert manuelt i første
1061 omgang, men ble senere installert automatisk via et script som Petter
1062 Reinholdtsen laget. Dette scriptet er så enkel å bruke at man er i
1063 gang med installasjonen i løpet av bare
5 minutter. Ikke nok med det,
1064 alt skjer helt automatisk. Alt i alt er jeg veldig fornøyd med
1065 resultatet av installasjonsprosessen. Raspberry Pi er en veldig svak
1066 maskin og det merkes godt når man har installert Skolelinux på
1067 den. Video og
3D-rendering fungerer utrolig dårlig, men nettsurfing og
1068 kontorprogrammer fungerer godt. Det kan derfor konkluderes med at
1069 datamaskinen er egnet for enkle oppgaver.
1071 <p
>Jeg syns det er viktig påpeke at dette kun er startfasen av en slik
1072 løsning. På markedet finnes det nå maskiner som har bedre hardware enn
1073 Raspberry Pi. Det er store muligheter for at man kan klare å
1074 installere Skolelinux på disse også, og da forsvinner nok mest
1075 sannsynlig ytelsesproblemene med Video og
3D rendering også.
</p
>
1077 <p
>Det ble også prøvd med en løsning som gjorde at Raspberry Pi
1078 fungerte som en tynnklient. Denne løsningen hadde langt bedre ytelse
1079 med tanke på hastighet og brukeropplevelse. Men også her var video og
1080 3D rendering dårlig. Det ble brukt en liten Linux distribusjon kalt
1081 <a href=

</a
> for å få til
1084 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
1086 <p
>Fordelen med Skolelinux er mange. At det er gratis er en stor
1087 fordel, men at det er så mange som er med på å utvikle det og
1088 vedlikeholde det er en enda større fordel. Allerede før jeg startet
1089 med prosjektet så jeg mange fordeler, og når jeg nærmet meg sluttfasen
1090 så jeg langt flere. At prosjektet skulle inneha en så høy kvalitet
1091 hadde jeg aldri trodd. En vanlig Skolelinux installasjon har de
1092 nødvendige programmene og funksjonen som både små og store skoler i
1093 tillegg til organisasjoner kan klare seg med. At prosjektet tilbyr en
1094 så komplett løsning er en kjempefordel. Installasjonen er knirkefri
1095 og det er svært enkelt å installere og komme i gang.
</p
>
1097 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
1099 <p
>Ulempene jeg ser med prosjektet er ryddigheten av websidene. Selv
1100 om websidene er enkle og konsise er det allikevel ikke appellerende i
1101 like stor grad som for eksempel
1102 <a href=
"http://www.ubuntu.com
">Ubuntu
</a
> sine sider. Deres side
1103 tilbyr, i tillegg til godt design og presentasjon, en nettbasert
1104 emulator av deres operativsystem. Dette er en stor fordel slik jeg ser
1105 det. Bortsett fra dette ser jeg absolutt ingen ulemper med
1106 Skolelinux-prosjektet.
</p
>
1108 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
1110 <p
>Til daglig er jeg en flittig bruker av det åpne media
1111 sentersystemet
<a href=
"http://xbmc.org/
">XBMC
</a
>. Det enorme
1112 samfunnet rundt dette prosjektet har gjort dette til et program som
1113 dekker alles behov. Man kan tilpasse det akkurat slik man vil både med
1114 tanke på utseende og funksjoner ved installere plug-ins eller
1117 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
1118 skoler til å ta i bruk fri programvare?
</strong
></p
>
1120 <p
>Strategien som burde brukes sett fra mine øyne er
1121 markedsføring. Jeg er sikker på at om flere skoler fikk et lite innsyn
1122 i hvor bra Skolelinux er så ville de ikke nølt med å gå over fra noe
1123 annet som koster de store summer. At skolelinux til de grader tilbyr
1124 en så komplett løsning bure komme frem. Enten via reklamekampanjer
1125 eller ved å sende ut folk til skoler for så å la skolenettverk
1126 ansvarlige få teste ut hvordan Skolelinux fungerer i praksis. Om det
1127 i tillegg ble utviklet gode websider og en emulator for å la brukere
1128 prøve operativsystemet ville nok dette ha styrket inntrykket
1129 betraktelig.

1223 <p
>Debian Edu, also known as Skolelinux, is a Linux distribution based
1224 on Debian providing an out-of-the box environment of a completely
1225 configured school network. Immediatly after installation a school
1226 server running all services needed for a school network is set up just
1227 waiting for users and machines being added via GOsa², a comfortable
1228 Web-UI. A netbooting environment is prepared using PXE, so after
1229 initial installation of the main server from CD, DVD or USB stick all
1230 other machines can be installed via the network.
</p
>
1232 <p
>This is the first test release based on Wheezy (which currently is
1233 not released yet). Basically this is an updated and slightly improved
1234 version compared to the Squeeze release.

1384 out-of-the box environment of a completely configured school

1386 services needed for a school network is set up just waiting for users
1387 and machines being added via GOsa², a comfortable Web-UI. A netbooting
1388 environment is prepared using PXE, so after initial installation of
1389 the main server from CD, DVD or USB stick all other machines can be
1390 installed via the network.

1516 the video show a walk-through of of the menu content, demonstration of
1517 a few programs and his view of our distribution.
</p

1519 <p
>There is also some really nice quotes (transcribed by me, might
1520 have heard wrong). While looking thought the Graphics menu:
</p
>
1523 "Basically everything you ever need in a school environment.
"
1526 <p
>And as a general evaluation of the entire distribution:
</p
>
1529 "So, yeah, a bit bloated. It kept all the Debian stuff in there, just
1530 to keep it nice and GNU. So, I do not want to go on about it, but
1531 lets give it
7 out of
10. I am not going to use it. That is because
1532 I am not deploying a school network. There may be some mythical
1533 feature to help you deploy Skolelinux on a school network.
"
1536 <p
>To bad he did not test the server profile, and discovered the PXE
1537 installation option. It make it possible to install only the main
1538 server from CD, and the rest of the machines via the net, and might be
1539 considered the mythical feature he talk about. :)
</p
>
1541 <p
>While looking through the menus, there is also this funny comment
1542 about the part of the K menu generated from the Debian menu subsystem:
1545 "[The K menu] have a special Debian section for software that no-one
1546 is going to look at, because it contain lots of junky stuff that you
1547 actually don
't need in the education distribution, but have just been
1548 included because it isn
't stripped out for some reason.
"
1551 <p
>I guess it is yet another argument for merging the Debian menu and
1552 Gnome/KDE desktop menu entries into
1553 <a href=
"http://wiki.debian.org/Proposals/DebianMenuUsingDesktopEntries
">one
1554 consistent menu system

1555 inconsistent menu systems.

>Etter en lang pause og travle uker har jeg endelig klart å få
1667 samlet et nytt intervju med en av folkene i
1668 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet.
1669 Denne gang er det Helge Tore Høyland, en mangeårig bidragsyter på
1670 epostlistene og ellers i prosjektet.
</p
>
1672 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
1674 <p
>Eg er IT-konsulent/teknikker hjå eit firma i Steinkjer med navn
1675 <a href=
"http://unoit.no/
">Uno IT
</a
>. Uno IT er eit lite firma som
1676 drifter nettverk og maskiner for små og mellomstore firma
1677 Steinkjer-området. Per dags dato er me
2 ansatte. Min faglege bakgrunn
1678 er Fagbrev som it-teknikker, samt nokre fag innen nettverk- og
1679 server-drift frå HiST og NTNU. Dagleg arbeid består i oppsett av nye
1680 maskiner og hjelp til sluttbrukere, samt oppsett og vedlikehold av eit
1681 vidt spekter av fagsystemer ute hjå kunder. Erfaring med Skolelinux
1682 har eg hatt i forbindelse med drifting av
1683 <a href=
"http://www.bjorkly.no/
">Bjørkly skule
</a
>, ein privat
1684 grunnskule i Namsos-området. I dag har skulen
65 elever,
15 lærere,
1
1685 hovedserver og ca
60 klienter som kjører halvtjukt. Eg har bygd og
1686 driftet systemet sidan summaren
2006.
</p
>
1688 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
1690 <p
>Eg kom i kontakt med Skolelinux-prosjektet via ein artikkel i eit
1691 fagblad, som eg ikkje lenger hugsar namnet på. I og med at eg allereie
1692 hadde pusla med nettverk for ein annan skule, fatta eg straks
1693 interesse for prosjektet.
</p
>
1695 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
1697 <p
>Fordelane med Skolelinux er sentralisert administrasjon og svært
1698 mange gode verktøy «ut av boksen». Veldig kjekt å kunne drifte
60
1699 klientar med berre å «bry» seg med ein server. Levetid for systemets
1700 hardware er og ein veldig fin effekt. I tillegg kjem fordelar som økt
1701 sikkerhet og mindre lisenskostnader. Etter min erfaring er det og
1702 mykje mindre driftskostnader med eit slikt system enn konkurrerande
1703 system, pga enkelhet med sentralisert administrasjon. På grunn av at
1704 Skolelinux er basert på Debian er det òg svært stabilt.
</p
>
1706 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
1708 <p
>Ulemper er mangel på vilje til å følge standarer ute i markedet,
1709 som fører til mangel på støtte til nokre mykje brukte ting. Flash og
1710 Java er typiske eksempel. Sidan Debian satsar på stabilitet framfor å
1711 ha nyeste pakke av eit program, kan ein i nokre tilfeller kome borti
1712 at program vert «for gamle». Det er spesielt nettlesaren som er
1713 utsett. Mangel på vilje til å utvikle pedagogisk programvare, i Noreg,
1714 for «alle» platformer fører òg til noko hovudbry.
</p
>
1716 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
1718 <p
>Til dagleg bruker eg svært mange forskjellige «fri programvare»
1719 program. Firefox, Thunderbird, Freecommander, ImgBurn, Clonezilla,
1720 OCS inventory, Icinga, Skolelinux, SystemRescueCD og mykje meir.
</p
>
1722 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
1723 skoler til å ta i bruk fri programvare?
</strong
></p
>
1725 <p
>Strategisk må ein fokusere på at sluttbruker eigentleg ikkje er så
1726 fokusert på at det er fri programvare men at det skal «berre fungere».
1727 Gjer det enkelt å bruker og ikkje minst å administrere. For Skolelinux
1728 sin del må ein få eit betre fokus på overganger. Utbytting av servere
1729 må gå meir automatisk, import og eksport av brukerbase og maskinbase
1730 med meir må kunne gå enkelt og oppgradering til neste versjon må bli
1731 mykje meir automatisk og gjennomtesta. Ein må unngå at ein må sette
1732 opp frå start når ein byter ut ein server eller oppgraderer til neste
1733 versjon. For å få Skolelinux til å bli eit betre alternativ for skular
1734 må ein ha fokus på nettlesaren. Denne må bli «up to date» og støtte
1735 dei protokollar og tillegg som vert brukt av forlag med meir. Etter
1736 kvart som meir og meir blir flytta ut i «skya» vert dette viktigare og
1737 viktigare. Ein kunne ynskje og jobbe for at forlag med fleire tar i
1738 bruk opne standarer, men inntil det skjer, må systemet kunne brukast
1739 mot desse fagsystema.
</p
>
1741 <p
>For meg har prosjektet med Skolelinux vore ein svært artig og
1742 lærerik prosess. Miljøet rundt er ikkje enormt stort, dog stort nok,
1743 men det er svært hjelpevillig og engasjert.

1780 interesting, as I am involved with several organizations where
1781 accounting is an issue, and I have not really become too friendly with
1782 the different web based systems we use. I find it hard to find what I
1783 look for in the menus and even harder try to get sensible data out of
1784 the systems. Ledger seem different. The accounting data is kept in
1785 text files that can be stored in a version control system, and there
1787 are at least
<a href=

1788 different implementations

"http://wiki.it-zukunft-schule.de/
">IT-Zukunft Schule
</a

1842 project out from maternity leave to conduct an interview. Give a warm
1843 welcome to Angela Fuß. :)
</p
>
1845 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
1847 <p
>I am a
39-year-old woman living in the very north of Germany near
1848 Denmark. I live in a patchwork family with
"my man
" Mike Gabriel, my
1849 two daughters, Mikes daughter and Mikes and my rather newborn son.
1851 <p
>At the moment - because of our little baby - I am spending most of
1852 the day by being a caring and organising mom for all the kids.
1853 Besides that I am really involved into and occupied with several inner
1854 growth processes: New born souls always bring the whole familiar
1855 system into movement and that needs time and focus ;-). We are also
1856 in the middle of buying a house and moving to it.
</p
>
1858 <p
>In
2013 I will work again in my job in a German foundation for
1859 nature conservation. I am doing public relation work there. Besides
1860 that - and that is the connection to Skolelinux / Debian Edu - I am
1861 working in our own school project
"IT-Zukunft Schule
" in North
1862 Germany. I am responsible for the quality assurance, the customer
1863 relationship management and the communication processes in the
1866 <p
>Since
2001 I constantly have been training myself in communication
1867 and leadership. Besides that I am a forester, a landscaping gardener
1868 and a yoga teacher.
</p
>
1870 <p
><strong
>How did you get in contact with the Skolelinux / Debian Edu
1871 project?
</strong
></p
>
1873 <p
>I fell in love with Mike ;-).
</p
>
1875 <p
>Very soon after getting to know him I was completely enrolled into
1876 Free Software. At this time Mike did IT-services for one newly
1877 founded school in Kiel. Other schools in Kiel needed concepts for
1878 their IT environment. Often when Mike came home from working at the
1879 newly founded school I found myself listening to his complaints about
1880 several points where the communication with the schools head or the
1881 teachers did not work. So we were clear that he would not work for
1882 one more school if we did not set up a structure for communication
1883 between him, the schools head, the teachers, the students and the
1886 <p
>Together with our friend and hardware supplier Andreas Buchholz we
1887 started to get an overview of free software solutions suitable for
1888 schools. One day before Christmas
2010 Mike and I had a date with Kurt
1889 Gramlich in Gütersloh. As Kurt and I are really interested in building
1890 networks of people and in being in communication we dived into
1891 Skolelinux and brought it to the first grammar schools in Northern
1894 <p
>For information about our school project you can read

"http://people.skolelinux.org/pere/blog/Debian_Edu_interview__Mike_Gabriel.html

1896 interview with Mike Gabriel
</a
>.
</p
>
1898 <p
><strong
>What do you see as the advantages of Skolelinux / Debian
1899 Edu?
</strong
></p
>
1901 <p
>First I have to say: I cannot answer this question technically. My
1902 answer comes rather from a social point of view.
</p
>
1904 <p
>The biggest advantage of Skolelinux / Debian Edu I see is the large
1905 and strong international community of Debian Developers in the
1906 background which is very alive and connected over mailinglists, blogs
1907 and meetings. My constant feeling for the Debian Community is: If
1908 something does not work they will somehow fix it. All is well
1909 ;-). This is of course a user experience. What I also get as a big
1910 advantage of Skolelinux / Debian Edu is that everybody who uses it and
1911 works with it can also contribute to it - that includes students,
1912 teachers, parents...
</p
>
1914 <p
><strong
>What do you see as the disadvantages of Skolelinux / Debian
1915 Edu?
</strong
></p
>
1917 <p
>I will answer this question relating to the internal structure of
1918 Skolelinux / Debian Edu.
</p
>
1920 <p
>What I see as a major disadvantage is that there is a gap between
1921 the group of developers for Debian Edu and the people who make the
1922 marketing, that means the people that bring Skolelinux to the
1923 schools. There is a lack of communication between these two groups and
1924 I think that does not really work for Skolelinux / Debian Edu.
</p
>
1926 <p
>Further I appreciate that Skolelinux / Debian Edu is known as a
1927 do-ocracy. Nevertheless I keep asking myself if at some points a
1928 democracy or some kind of hierarchical project structure would be good
1929 and helpful. I am also missing some kind of contact between the
1930 Skolelinux / Debian Edu communities in Europe or on an international
1931 level. I think it would be good if there was more sharing between the
1932 different countries using Skolelinux / Debian Edu.
</p
>
1934 <p
><strong
>Which free software do you use daily?
</strong
></p
>
1936 <p
>On my laptop I am still using an Ubuntu
10.04 with a Gnome Desktop
1937 on. As applications I use Openoffice.org, Gedit, Firefox, Pidgin,
1938 LaTeX and GnuCash. For mails I am using Horde. And I am really fond of
1939 my N900 running with Maemo.
</p
>
1941 <p
><strong
>Which strategy do you believe is the right one to use to
1942 get schools to use free software?
</strong
></p
>
1944 <p
>I am really convinced that in our school project
"IT-Zukunft
1945 Schule
" we have developed (and keep developing) a great way to get
1946 schools to use Free Software. We have written a detailed concept for
1947 that so I cannot explain the whole thing here. But in a nutshell the
1948 strategy has three crucial pillars:
</p
>
1952 <li
>We really take time to get what sort of stories, questions and
1953 concerns the schools head and the teachers have about using different
1954 kinds of IT and we take time to enrol them into Free Software.
</li
>
1956 <li
>Our solution for schools is never just technical. In the centre
1957 are always the people who are going to use the software. From the very
1958 beginning of the planning for a school, we tell the schools head that
1959 they are paying us not only for a technical solution for their school,
1960 they also pay us for leading all the communication processes
1961 needed. If they do not want that, we are not working with them because
1962 we cannot give a guarantee for the quality of our work then.
</li
>
1964 <li
>Another focus lies in the training of teachers and students in
1965 co-administrating the IT-System at their school. They start getting in
1966 contact with the Skolelinux / Debian Edu community and they get the
1967 offer to become more and more independent from us.

1990 <p
>I sommer (
2012-
07-
23) hadde Fremover et oppslag om at Narvik
1991 kommune hadde spart mellom
10 og
20 millioner kroner de siste årene på
1992 å bruke Skolelinux på sine skoler. Harstad har også tatt i bruk
1993 Skolelinux på alle sine skoler. Som tidligere Ballangsværing gledet
1994 det meg stort å se at skoleløsningen vi har utviklet siden
2001 tas i
1995 bruk i området der jeg vokste opp, og dermed bidrar til en bedre og
1996 billigere skolehverdag.
</p
>
1998 <p
>Skolelinux er en komplett IT-løsning for elevnettverket på en
1999 skole, med både nettverkstjenester og løsning for elevmaskiner med
2000 pedagogisk programvare, som tillater en å øke levetiden på en
2001 datamaskin i skolen med mange år. En undersøkelse publisert i mars
2002 2012 viste at de
56 norske skolene som har offentliggjort at de bruker
2003 Skolelinux eller annen Linuxutgave hadde
36% større PC-tetthet enn
2004 landsgjennomsnittet, når en ser på tall rapportert til Grunnskolens
2005 Informasjonssystem. I følge Paul Reidar Løsnesløkken, IKT-konsulent i
2006 Nord-Odal, fungerer datamaskiner godt til de er
8 til
10 år gamle.
</p
>
2008 <p
>I høst (
2012-
09-
29) fortalte Fremover hvordan Ballangen kommune har
2009 opparbeidet seg
20 millioner i underskudd og nok havner på Robek-lista
2010 fra nyttår. Kanskje Ballangen også burde ta i bruk Skolelinux for å
2011 spare penger? Hvis kommunen mangler kompetanse lokalt på Linux finnes
2012 det kommersielle selskaper som tilbyr driftstjenester rundt
2013 Skolelinux, og jeg bør vel avsløre at jeg selv er involvert i et av
2014 dem, Skolelinux Drift AS. Kommunen kan dermed få hjelp hvis de ikke
2015 ønsker å bygge opp egen kompetanse.

2045 stavekontrollbrukere og korrekturlesere, og endel feil har sneket seg

2086 noe utviklerne er veldig glade for.

2088 <p
>Den største endringen er at byggesystemet for stavekontrollen er
2089 skrevet om til å akseptere ord med bindestrek (f.eks. «e-post»). Litt
2090 over
10.000 slike ordformer er lagt til i orddatabasen. I tillegg er
2091 det kommet en del nye ord og rettelser rapportert inn av de frivillige
2092 som gjennomfører korrektur av orddatabasen i prosjektet. For å få

>After a long break in my row of interviews with people in the
2183 <a href=

">Debian Edu and Skolelinux
</a
>
2184 community, I finally found time to wrap up another. This time it is
2185 Giorgio Pioda, which showed up on the mailing list at the start of
2186 this year, asking questions and inspiring us to improve the first time
2187 administrators experience with Skolelinux. :) The interview was
2188 conduced in May, but I only found time to publish it now.
</p

2190 <p
><strong
>Who are you, and how do you spend your days?
</strong

2192 <p
>I have a PhD in chemistry but since several years I work as teacher
2193 in secondary (
15-
18 year old students) and tertiary (a kind of
"light
"
2194 university) schools. Five years ago I started to manage a Learning
2195 Management Service server and slowly I got more and more involved with
2196 IT.
3 years ago the graduating schools moved completely to Linux and I
2197 got the head of the IT for this. The experience collected in chemistry
2198 labs computers (for example NMR analysis of protein folding) and in
2199 the IT-courses during university where sufficient to start. Self
2200 training is anyway very important
</p
>
2202 <p
>I live in the Italian speaking part of Switzerland, and the
2203 <a href=
"http://www.spse.ch/
">SPSE school
</a
> (secondary) is a very
2204 special sport school for young people who try to became sport pro (for
2205 all sports, we have dozens of disciplines represented) and we are
2206 recognised by the Olympic Swiss Organisation.
2208 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2209 project?
</strong
></p
>
2211 <p
>Looking for Linux / Primary Domain Controller (PDC) I found it
2212 already several years ago. But since the system was still not
2213 Kerberized and since our schools relies strongly on laptops I didn
't
2214 use it. I plan to introduce it in the next future, probably for the
2215 next school year, since the squeeze release solved this security
2218 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2219 Edu?
</strong
></p
>
2221 <p
>Many. First of all there is a strong and living community that is
2222 very generous for help and hints. Chat help is crucial, together with
2223 the mailing list. Second. With Skolelinux you get an already well
2224 engineered platform and you don
't have to start to build up your PDC
2225 and your clients from GNU/scratch; I
've already done this once and I
2226 can tell it, it is hard. Third, since Skolelinux is a standard
2227 platform, it is way easier to educate other IT people and even if the
2228 head IT is sick another one could pick up the task without too much
2231 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2232 Edu?
</strong
></p
>
2234 <p
>The only real problem I see is that it is a little too less
2235 flexible at client level. Debian stable is rocky and desirable, but
2236 there are many reasons that force for another choice. For example the
2237 need of new drivers for new PC, or the need for a specific OS for some
2238 devices that have specific software packages for another specific
2239 distribution (I have such a case for whiteboards that have only
2240 Ubuntu packages). Thus, I prepared compatibility packages educlient
2241 and eduroaming, hoping not to use them ;-)
</p
>
2243 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2245 <p
>I have a Debian Stable PDC at school (Kerberos, NIS, NFS) with
2246 mixed Debian and Ubuntu clients. If you think that this triad
2247 combination is exotic... well I discovered right yesterday that
2248 <a href=
"http://moo.nac.uci.edu/~hjm/Perceus-Report.html
">Perceus
</a
>
2249 has the same...
</p
>
2251 <p
>For myself I run Debian wheezy/sid, but this combination is good
2252 only I you have enough competence to fix stuff for yourself, if
2253 something breaks. Daily I use texmacs, gnumeric, a little bit of R
2254 statistics, kmplot, and less frequently OpenOffice.org.
</p
>
2256 <p
><strong
>Which strategy do you believe is the right one to use to
2257 get schools to use free software?
</strong
></p
>
2259 <P
>I think that the only real argument that school managers
"hear
" is
2260 cost reduction. They don
't give too much weight on quality, stability,
2261 just because they are normally not open to change.
</p
>
2263 <p
>Students adapts very quickly to GNU/Linux (and for them being able
2264 to switch between different OS is a plus value); teachers and managers
2265 don
't.
</p
>
2267 <p
>We decided to move to Linux because students at our school have own
2268 laptop and we have the responsibility to keep the laptop ready to use;
2269 we were really unsatisfied with Microsoft since every Monday we had
20
2270 machine to fix for viral infections... With Linux this has been
2271 reduced to zero, since people installs almost only from official
2272 repositories. I think that our special needs brought us to Linux.
2273 Those who don
't have such needs will hardly move to Linux.

4 og

2287 henvendelser til avisen for å få artikkelen på nett har så langt ikke
2288 vært vellykket.
</p
>
2290 <p
>Artikkelen med tittelen
"Narvik kommune bruker gratisprogram i
2291 skolen - Har spart millioner
", forteller om hvordan bruken av
2292 Skolelinux er en stor suksess i Narvik siden det ble tatt i bruk i
2293 2004. Her er noen fine sitater:
</p
>
2296 "- Skolelinux har spart kommunen for store pengesummer, millionbeløp,
2297 som de heller kan bruke på andre ting, sier IKT-konsulent Viggo
2301 <p
>Avisen forteller at de har fått tilgang til beregninger som viser
2302 at Narvik kommune har spart noe mellom
10 og
20 millioner kroner de
2303 siste
8 årene på å bruke Skolelinux, og fortsetter:
</p
>
2307 "Regnestykket tar høyde for sparte kostnader til lisenser som medfølger
2308 de alternative operativsystemene, lavere driftskostnader og lengre
2309 levetid på datautstyret. Totalt har Narvikskolen en maskinpark på
2310 1600 maskiner fordelt på de
11 skolene fra Skjomen i sør til Bjerkvik
2315 <p
>Viggo Fedreheim sier dette om hvor noe av gevinsten kommer fra:
</p
>
2318 "- Vi kan gjenbruke gamle maskiner i skolen som er for dårlig andre
2319 steder i kommunen der de ikke bruker Skolelinux. Levetiden på en
2320 datamaskin blir
3-
5 år lenger med Skolelinux. Vi kaller det for
2321 grønn IT, miljøvennlig IT.
"
2324 <p
>Her er det mulighet for flere kommuner å få et godt IT-system på
2325 skolene, hvis de er villige til å forsøke. De som ikke har kompetanse
2326 innomhus kan kjøpe det fra en av de kommersielle leverandørene av

>I
'm a
44 year old country guy that have been working
12 years at
2402 the same school as
50% IT-manager and
50% Teacher. My educational
2403 background is fil.kand in history and religious beliefs, an exam as a
2404 "folkhighschool
" teacher, that is, for teaching grownups. In
2405 Norwegian I believe it
's called
"Vuxenupplaring
". I also have a master
2406 in
"Technology and social change
". So I
'm not really a tech guy, I
2407 just like to study how humans and technology interact and that is my
2408 perspective when working with IT.
</p
>
2410 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2411 project?
</strong
></p
>
2413 I have followed the Skolelinux project for quite some time by
2414 now. Earlier I tested out the K12-LTSP project, which we used for some
2415 time, but I really like the idea of having a distribution aimed to be
2416 a complete solution for schools with necessary tools integrated. When
2417 K12-LTSP abandoned that idea some years ago, I started to look more
2418 seriously into Skolelinux instead.
2420 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2421 Edu?
</strong
></p
>
2423 The big point of Skolelinux to me is that it is a complete
2424 distribution, ready to install. It has LDAP-support, MS Windows
2425 integration tools and so forth already configured, saving an
2426 administrator a lot of time and headache. We were using another Linux
2427 based thin-client system called Thinlinc, that has served us very
2428 well. But that Skolelinux is based on VNC and LTSP, to me, is better
2429 when it comes to the kind of multimedia used in schools. That is
2430 showing videos from Youtube or educational TV. It is also easier to
2431 mix thin clients with workstations, since the user settings will be the
2432 same. In our VNC-based solution you had to
"beat around the bush
" by
2433 setting up a second, hidden, home-directory for user settings for the
2434 workstations, because they will be different from the ones used on the
2435 thin clients. Skolelinux support for diskless workstations are very
2436 convenient since a school today often need to use a class room
2437 projector showing videos in full screen. That is easily done with a
2438 small integrated media computer running as a diskless workstation. You
2439 have only two installs to update and configure. One for the thin
2440 clients and one for the workstations. Also saving a lot of time. Our
2441 old system was also based on Redhat and CentOS. They are both very
2442 nice distributions, but they are sometimes painfully slow when it
2443 comes to updating multimedia support and multimedia programs (even
2444 such as Gimp), leaving us with a bit
"oldish
" applications. Debian is
2447 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2448 Edu?
</strong
></p
>
2450 <p
>Debian is a bit too quick when it comes to updating. As an example
2451 we use old HP terminals as thinclients, and two times already this
2452 year (
2012) the updates you get from the repositories has stopped
2453 sound from working with them. It
's a kernel/ALSA issue. So you have
2454 to be more careful properly testing the updates before you run them in
2455 a production environment. This has never happened with CentOS.
</p
>
2457 <p
>I also would like to be able to set my own domain-settings at
2458 install time. In Skolelinux they are kind of hard coded into the
2459 distribution, when it comes to LDAP and at least samba integration.
2460 That is more a cosmetic/translation issue, and not a real problem.
2461 Running MS Windows applications within the Skolelinux environment needs
2462 to be better supported. That is, running them seamlessly via RDP, and
2463 support for single-sign on. That will make the transition to free
2464 software easier, because you can keep the applications you really
2465 need. No support will make it impossible if you work in a school where
2466 some applications can
't be open source. As for us we really need to
2467 run Adobe InDesign in our journalist classes. We run a journalist
2468 education, and is one of the very few non university ones that is ok:d
2469 by Svenska journalistförbundet (Swedish journalist association). Our
2470 education gives the pupils the right of membership there, once they
2471 are done. This is important if you want to get a job.
</p
>
2473 <p
>Adobe InDesign is the program most commonly used in newspapers and
2474 magazines. We used Quark Express before, but they seem to loose there
2475 market to Adobe. The only
"equivalent
" to InDesign in the opensource
2476 world is Scribus, and its not advanced enough. At least not according
2477 to the teacher. I think it would be possible to use it, because they
2478 are not supposed to learn a program, they are supposed to learn how to
2479 edit and compile a newspaper. But politically at our school we are not
2480 there yet. And Scribus lacks a lot of things you find i InDesign.
</p
>
2482 <p
>We used even a windows program for sound editing when it comes to
2483 the radio-journalist part. The year to come we are going to try
2484 Audacity. That software has the same kind of limitations compared to
2485 Adobe Audition, but that teacher is a bit more open minded. We have
2486 tried Ardour also, but that instead is more like a music studio
2487 program, not intended for the kind of editing taking place in a radio
2488 studio. Its way to complex and the GUI is to scattered when you only
2489 want to cut, make pass-overs, add extra channels and normalise. Those
2490 things you can do in Audacity, but its not as easy as in Audition. You
2491 have to do more things manually with envelopes, and that is a bit old
2492 fashion and timewasting. Its also harder to cut and move sound from
2493 one channel to another, which is a thing that you do frequently
2494 because you often find yourself needing to rearrange parts of the
2495 sound file.
</p
>
2497 <p
>So, I am not sure we will succeed in replacing even Audition, but we
2498 will try. The problem is the students have certain expectations when
2499 they start an education towards a profession. So the programs has to
2500 look and feel professional. Good thing with radio, there are many
2501 programs out there, that radio studios use, so its not as standardised
2502 as Newspaper editing. That means, it does not really matter what
2503 program they learn, because once they start working they still have to
2504 learn the program the studio uses, so instead focus has to be to learn
2505 the editing part without to much focus on a specific software.
</p

2507 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2509 <p
>Myself I
'm running Linux Mint, or Ubuntu these days. I use almost
2510 only open source software, and preferably Linux based. When it comes
2511 to most used applications its OpenOffice, and Firefox (of course ;)
2514 <p
><strong
>Which strategy do you believe is the right one to use to
2515 get schools to use free software?
</strong
></p
>
2517 <p
>To get schools to use free software there has to be good open
2518 source software that are windows based, to ease the transition. But
2519 it
's also very important that the multimedia support is working
2520 flawlessly. The problems with Youtube, Twitter, Facebook and whatever
2521 will create problems when it comes to both teachers and
2522 students. Economy are also important for schools, so using thin
2523 clients, as long as they have good multimedia support, is a very good
2524 idea. It
's also important that the open source software works even for
2525 the administration. It
's hard to convince the teachers to stick with
2526 open source, if the principal has to run Windows. It also creates a
2527 problem if some classes has to use Windows for there tasks, since that
2528 will create a difference in
"status
" between classes, so a good
2529 support for running windows applications via the thin client (Linux)
2530 desktop is essential. At least at our school, where we have mixed
2531 level of educations, from high-school to journalist-school.

2533 <p

2012-

09 08:

2534 useful sources related to Free Software for radio stations: the LWN
2535 article

2538 claim to be a Free open source radio automation software and
2539 <a href=

2540 be complete radio broadcast automation solution. All of them seem
2541 useful to the aspiring radio producer.

>In the Debian Edu / Skolelinux project, we have realised that one
2551 of the major blockers for the project success is the purchasing skills
2552 in schools and municipalities. We provide what the happy users of
2553 Debian Edu / Skolelinux say they need and to a lower cost than the
2554 alternatives, and yet so few schools decide to use our solution. I
2555 was pleased to discover the same observation done by mySociety and Tom
2556 Steinberg in his blog post
2557 "<a href=

2559 spending of your tax money.
</p

2561 <p
>Of course there are other factors involved as well, like our
2562 projects bad marketing skills and the Linux community fragmentation
2563 causing worry with the people on the outside, so we as a project need
2564 to keep working hard to gain users, but it is a up-hill battle when
2565 public decision makers are unable to understand computer system
2566 purchases.

40 år. Utdannet biolog med ymse
2768 fag på siden. Har jobbet som lærer der jeg var driftsansvarlig på
2769 Ulsrud VGS i Oslo. Senere eide og jobbet jeg flere år i Linuxlabs AS,
2770 som jeg solgte til Redpill Linpro AS (den gangen Linpro AS). I dag
2771 jobber jeg med ulike investeringer, hovedsaklig i eiendom, men også i
2772 en del ulike IT-relaterte bedrifter.

2776 <p
>Fruen og jeg dro på en lengre seiltur i
2000, der jeg måtte ha
"noe
2777 å gjøre
" under hjemturen over Atlanteren. Jeg kjøpte et par bøker om
2778 Linux i en bokhandel i New York og ble veldig fascinert. Etter
2779 hjemkomsten begynte jeg å jobbe på Ulsrud VGS, som naturfagslærer, men
2780 som IT-interessert ble jeg fort en del av den nye IT-satsningen som
2781 skulle løfte Ulsrud og gi skolen en bedre rykte. Vi hadde ganske
2782 mange maskiner, som gikk på Win98 og to servere som ble oppgradert til
2783 Win2000. Systemene var ustabil og dårlige. På leting etter noe
2784 bedre, uten å knekke ryggen økonomisk, kom jeg over
"Linux i Skolen
"
2785 og Skolelinux. Jeg tok kontakt med miljøet og en gjeng møtte opp på
2786 skolen, der vi gjorde en liten testinstallasjon. Etter et par år var
2787 ryggraden på skolen Linux (Skolelinux) og vi hadde flere hundre
2788 maskiner, både tynne klienter (gamle og nye), bærbare (Debian) og noen
2789 stasjonære (Win2000). På et tidspunkt var Ulsrud den råeste IT-skolen
2790 og det irriterte skolesjefen i Oslo, da de satset hardt på

>Hva er fordelene med Skolelinux slik du ser det?
</strong

>
2795 <p
>Det som gjorde at vi fikk inn Skolelinux var ene og alene
2796 økonomiske. Det faktum at vi slapp å kjøpe masse nye lisenser og at
2797 vi kunne bruke gammel hardware. Alt i alt gjorde dette at vi sparte
2798 mye, men i stede for å bruke mindre på IT brukte vi det vi sparte på å
2799 skaffe mer hardware og på den måten gi det beste tilbudet i landet til
2800 våre elever. For oss som driftet var det himmel å ha et system som
2801 gikk å administrere sentralt og effektivt. Det var heller ikke så
2802 dumt at vi kunne
"låse
" maskinene mer effektivt enn vi kunne med
2803 Microsoft Windows, slik at vi slapp mye feil og problemer som ble
2804 forårsaket av
"kreative
" elever.

2806 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

2808 <p
>Det vi slet med var mangelen av en del programmer lærerne ville ha.
2809 Husker ikke alle, men det var et knippe med pedagogiske programmer de
2810 ikke fikk. I dag tror jeg det problemet er langt mindre da det meste
2811 av disse kjøres gjennom nettleseren.

2815 <p
>Jeg bruker mye Apple i dag og er ikke så stolt av det, men jeg har
2816 både OpenOffice, Firefox og en del andre programmer på den bærbare.
2817 Firefox brukes mest av disse. På Apple-serveren hjemme bruker jeg
2818 HandBrake mye, og jeg har installert OpenWRT på flere av
2819 basestasjonene både hjemme og på jobben. I tillegg til det har jeg i
2820 flere år finansiert et prosjekt som heter
2821 <a href=
"http://www.found.no/
">Found IT
</a

2822 vi lager et rammeverk for søk, der alt vi bruker fri programvare. Det
2823 er Alex Brasetvik som er daglig leder i Found IT.

2826 skoler til å ta i bruk fri programvare?
</strong

2828 <p
>Når det gjelder IT og skole er fortsatt økonomi veldig viktig. Så
2829 man må oppfylle minimumskravene (ikke være best, men bra nok) og selge
2830 seg inn på hvor mye man sparer. Det betyr selvsagt at man sparer på
2831 lisenser, men også på driftsinnsats. Men nå når jeg ikke er en aktiv
2832 del av miljøet lenger hører jeg nesten ingen ting om fri programvare.
2833 Jeg stiller meg da spørsmålet om det har blitt stille rundt miljøet,
2834 eller om jeg kun så det tydeligere før når jeg var aktiv? Uansett er
2835 det for stille rundt Skolelinux-prosjektet nå.

2845 another interview with the people behind
2846 <a href=
"http://www.skolelinux.org/
">Debian Edu and Skolelinux
</a
>.
2847 This time we get to know José Luis Redrejo Rodríguez, one of our great
2848 helpers from Spain. His effort was the reason we added support for
2849 several desktop types (KDE, Gnome and most recently LXDE) in Debian
2850 Edu, and have all of these available in the recently published

2854 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
2856 <p
>I
'm a father, teacher and engineer who is working for the Education
2857 ministry of the Region of Extremadura (Spain) in the implementation of
2858 ICT in schools
</p
>
2860 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
2861 project?
</strong
></p
>
2863 <p
>At
2006, I verified that both, we in Extremadura and Skolelinux
2864 project, had been working in parallel for some years, doing very
2865 similar things, using very similar tools and with similar targets, so
2866 I decided it was time to join forces as much as possible.
</p
>
2868 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
2869 Edu?
</strong
></p
>
2871 <p
>A community of highly skilled experts working together, with a
2872 really open schema of collaboration and work. I really love the
2873 concepts of Do-ocracy and Merit-ocracy and the way these concepts are
2874 been used everyday inside Debian Edu.
</p
>
2876 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
2877 Edu?
</strong
></p
>
2879 <p
>Sometimes the differences in the implementations, laws or
2880 economical and technical resources in the different countries don
't
2881 allow us to agree in the same solution for all of us, and several
2882 approaches are needed, what is a waste of effort. Also, there is a
2883 lack of more man power to be able to follow the fast evolution of the
2884 technologies in school.
</p
>
2886 <p
><strong
>Which free software do you use daily?
</strong
></p
>
2888 <p
>Debian, of course, and due to my kind of job I am most of my time
2889 between Iceweasel,
<a href=

</a

">Terminator
</a
>.
</p
>
2892 <p
><strong
>Which strategy do you believe is the right one to use to
2893 get schools to use free software?
</strong
></p
>
2895 <p
>I think there is not a single strategy because there are very
2896 different scenarios: schools with mixed proprietary and free
2897 environments, schools using only workstations, other schools using
2898 laptops, netbooks, tablets, interactive white-boards, etc.
</p
>
2900 <p
>Also the range of ages of the students is very broad and you can
2901 not use the same solutions for primary schools and secondary or even
2902 universities. So different strategies are needed.
</p
>
2904 <p
>But, looking at these differences, and looking back to the things
2905 we
've done and implemented, and the places were we have spent most of
2906 our forces, I think we should focus as much as possible in free
2907 multi-platform environments, using only standards tools, and moving
2908 more and more to Internet or network solutions that could be deployed
2909 using wireless. I think we
'll see more and more personal devices in
2910 the schools, devices the students and teachers will take home with
2911 them, so the solutions must be able to be taken at home and continue
2912 working there.

"http://www.debian.org/News/

20120311.nb.html
">Debian Edu
2923 based on Squeeze
</a
>, I came across some issues that should be
2924 addressed in the Wheezy release. I finally found time to wrap up my
2925 notes and provide quick summary of what I found, with a bit
2926 explanation.
</p
>
2930 <li
>We need to rewrite our package installation framework, as tasksel
2931 changed from using tasksel tasks to using meta packages (aka packages
2932 with dependencies like our education-* packages), and our installation
2933 system depend on tasksel tasks in
2934 /usr/share/tasksel/debian-edu-tasks.desc for package
2935 installation.
</li
>
2937 <li
>Enable Kerberos login for more services. Now with the Kerberos
2938 foundation in place, we should use it to get single sign on with more
2939 services, and avoiding unneeded password / login questions. We should
2940 at least try to enable it for these services:
2943 <li
>CUPS for admins to add/configure printers and users when using
2945 <li
>Nagios for admins checking the system status.
</li
>
2946 <li
>GOsa for admins updating LDAP and users changing their passwords.
</li
>
2947 <li
>LDAP for admins updating LDAP.
</li
>
2948 <li
>Squid for users when exam mode / filtering is active.
</li
>
2949 <li
>ssh for admins and users to save a password prompt.
</li
>
2951 </ul
></li
>
2953 <li
>When we move GOsa to use Kerberos instead of LDAP bind to
2954 authenticate users, we should try to block or at least limit access to
2955 use LDAP bind for authentication, to ensure Kerberos is used when it
2956 is intended, and nothing fall back to using the less safe LDAP bind
</li
>
2958 <li
>Merge debian-edu-config and debian-edu-install. The split made
2959 sense when d-e-install did a lot more, but these days it is just an
2960 inconvenience when we update the debconf preseeding values.
</li
>
2962 <li
>Fix partman-auto to allow us to abort the installation before
2963 touching the disk if the disk is too small. This is
2964 <a href=
"http://bugs.debian.org/
653305">BTS report #
653305</a
> and the
2965 d-i developers are fine with the patch and someone just need to apply
2966 it and upload. After this is done we need to adjust
2967 debian-edu-install to use this new hook.
</li
>
2969 <li
>Adjust to new LTSP framework (boot time config instead of install
2970 time config). LTSP changed its design, and our hooks to install
2971 packages and update the configuration is most likely not going to work
2974 <li
>Consider switching to NBD instead of NFS for LTSP root, to allow
2975 the Kernel to cache files in its normal file cache, possibly speeding
2976 up KDE login on slow networks.
</li
>
2978 <li
>Make it possible to create expired user passwords that need to
2979 change on first login. This is useful when handing out password on
2980 paper, to make sure only the user know the password. This require
2981 fixes to the PAM handling of kdm and gdm.
</li
>
2983 <li
>Make GUI for adding new machines automatically from sitesummary.
2984 The current command line script is not very friendly to people most
2985 familiar with GUIs. This should probably be integrated into GOsa to
2986 have it available where the admin will be looking for it..
</li
>
2988 <li
>We should find way for Nagios to check that the DHCP service
2989 actually is working (as in handling out IP addresses). None of the
2990 Nagios checks I have found so far have been working for me.
</li
>
2992 <li
>We should switch from libpam-nss-ldapd to sssd for all profiles
2993 using LDAP, and not only on for roaming workstations, to have less
2994 packages to configure and consistent setup across all profiles.
</li
>
2996 <li
>We should configure Kerberos to update LDAP and Samba password
2997 when changing password using the Kerberos protocol. The hook was
2998 requested in
<a href=
"http://bugs.debian.org/
588968">BTS report
2999 #
588968</a
> and is now available in Wheezy. We might need to write a
3000 MIT Kerberos plugin in C to get this.
</li
>
3002 <li
>We should clean up the set of applications installed by default.
3005 <li
>reduce the number of chemistry visualisers
</li
>
3006 <li
>consider dropping xpaint
</li
>
3007 <li
>and probably more?
</li
>
3008 </ul
></li
>
3010 <li
>Some hardware need external firmware to work properly. This is
3011 mostly the case for WiFi network cards, but there are some other
3012 examples too. For popular laptops to work out of the box, such
3013 firmware need to be installed from non-free, and we should provide
3014 some GUI to do this. Ubuntu already have this implemented, and we
3015 could consider using their packages. At the moment we have some
3016 command line script to do this (one for the running system, another
3017 for the LTSP chroot).
</li
>
3020 <li
>In Squeeze, we provide KDE, Gnome and LXDE as desktop options. We
3021 should extend the list to Xfce and Sugar, and preferably find a way to
3022 install several and allow the admin or the user to select which one to
3025 <li
>The golearn tool from the goplay package make it easy to check out
3026 interesting educational packages. We should work on the package
3027 tagging in Debian to ensure it represent all the useful educational
3028 packages, and extend the tool to allow it to use packagekit to install
3029 new applications with a simple mouse click.
</li
>
3031 <li
>The Squeeze version got half a exam solution already in place,
3032 with the introduction of iptable based network blocking, but for it to
3033 be a complete exam solution the Squid proxy need to enable
3034 filtering/blocking as well when the exam mode is enabled. We should
3035 implement a way to easily enable this for the schools that want it,
3036 instead of the
"it is documented
" method of today.
</li
>
3038 <li
>A feature used in several schools is the ability for a teacher to
3039 "take over
" the desktop of individual or all computers in the room.
3040 There are at least three implementations,
3041 <a href=
"italc.sourceforge.net/
">italc
</a
>,
3042 <a href=
"http://www.itais.net/help/en/
">controlaula
</a
> og
3043 <a href=
"http://www.epoptes.org/
">epoptes
</a
> and we should pick one of
3044 them and make it trivial to set it up in a school. The challenges is
3045 how to distribute crypto keys and how to group computers in one room
3046 and how to set up which machine/user can control the machines in a
3047 given room.
</li
>
3049 <li
>Tablets and surf boards are getting more and more popular, and we
3050 should look into providing a good solution for integrating these into
3051 the Debian Edu network. Not quite sure how. Perhaps we should
3052 provide a installation profile with better touch screen support for
3053 them, or add some sync services to allow them to exchange
3054 configuration and data with the central server. This should be
3055 investigated.

>Who are you, and how do you spend your days?
</strong
></p
>
3078 <p
>My name is Mike Gabriel, I am
38 years old and live near Kiel,
3079 Schleswig-Holstein, Germany. I live together with a wonderful partner
3080 (Angela Fuß) and two own children and two bonus children (contributed
3081 by Angela).
</p
>
3083 <p
>During the day I am part-time employed as a system administrator
3084 and part-time working as an IT consultant. The consultancy work
3085 touches free software topics wherever and whenever possible. During
3086 the nights I am a free software developer. In the gaps I also train in
3087 becoming an osteopath.
</p
>
3089 <p
>Starting in
2010 we (Andreas Buchholz, Angela Fuß, Mike Gabriel)
3090 have set up a free software project in the area of Kiel that aims at
3091 introducing free software into schools. The project
's name is
3092 "IT-Zukunft Schule
" (IT future for schools). The project links IT
3093 skills with communication skills.
</p
>
3095 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3096 project?
</strong
></p
>
3098 <p
>While preparing our own customised Linux distribution for
3099 "IT-Zukunft Schule
" we were repeatedly asked if we really wanted to
3100 reinvent the wheel. What schools really need is already available,
3101 people said. From this impulse we started evaluating other Linux
3102 distributions that target being used for school networks.
</p
>
3104 <p
>At the end we short-listed two approaches and compared them: a
3105 commercial Linux distribution developed by a company in Bremen,
3106 Germany, and Skolelinux / Debian Edu. Between
12/
2010 and
03/
2011 we
3107 went to several events and met people being responsible for marketing
3108 and development of either of the distributions. Skolelinux / Debian
3109 Edu was by far much more convincing compared to the other product that
3110 got short-listed beforehand--across the full spectrum. What was most
3111 attractive for me personally: the perspective of collaboration within
3112 the developmental branch of the Debian Edu project itself.
</p
>
3114 <p
>In parallel with this, we talked to many local and not-so-local
3115 people. People teaching at schools, headmasters, politicians, data
3116 protection experts, other IT professionals.
</p
>
3118 <p
>We came to two conclusions:
</p
>
3120 <p
>First, a technical conclusion: What schools need is available in
3121 bits and pieces here and there, and none of the solutions really fit
3122 by
100%. Any school we have seen has a very individual IT setup
3123 whereas most of each school
's requirements could mapped by a standard
3124 IT solution. The requirement to this IT solution is flexibility and
3125 customisability, so that individual adaptations here and there are
3126 possible. In terms of re-distributing and rolling out such a
3127 standardised IT system for schools (a system that is still to some
3128 degree customisable) there is still a lot of work to do here
3129 locally. Debian Edu / Skolelinux has been our choice as the starting
3132 <p
>Second, a holistic conclusion: What schools need does not exist at
3133 all (or we missed it so far). There are several technical solutions
3134 for handling IT at schools that tend to make a good impression. What
3135 has been missing completely here in Germany, though, is the enrolment
3136 of people into using IT and teaching with IT.
"IT-Zukunft Schule
"
3137 tries to provide an approach for this.
</p
>
3139 <p
>Only some schools have some sort of a media concept which explains,
3140 defines and gives guidance on how to use IT in class. Most schools in
3141 Northern Germany do not have an IT service provider, the school
's IT
3142 equipment is managed by one or (if the school is lucky) two (admin)
3143 teachers, most of the workload these admin teachers get done in there
3144 spare time.
</p
>
3146 <p
>We were surprised that only a very few admin teachers were
3147 networked with colleagues from other schools. Basically, every school
3148 here around has its individual approach of providing IT equipment to
3149 teachers and students and the exchange of ideas has been quasi
3150 non-existent until
2010/
2011.
</p
>
3152 <p
>Quite some (non-admin) teachers try to avoid using IT technology in
3153 class as a learning medium completely. Several reasons for this
3154 avoidance do exist.
</p
>
3156 <p
>We discovered that no-one has ever taken a closer look at this
3157 social part of IT management in schools, so far. On our quest journey
3158 for a technical IT solution for schools, we discussed this issue with
3159 several teachers, headmasters, politicians, other IT professionals and
3160 they all confirmed: a holistic approach of considering IT management
3161 at schools, an approach that includes the people in place, will be new
3162 and probably a gain for all.
</p
>
3164 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3165 Edu?
</strong
></p
>
3167 <p
>There is a list of advantages: international context, openness to
3168 any kind of contributions, do-ocracy policy, the closeness to Debian,
3169 the different installation scenarios possible (from stand-alone
3170 workstation to complex multi-server sites), the transparency within
3171 project communication, honest communication within the group of
3172 developers, etc.

3181 client installations on top of a plain vanilla Debian installation
3182 should become possible sometime in the near future, one could think
3183 about splitting the very complex package debian-edu-config into
3184 several portions (to make it easier for new developers to
3185 contribute).
</p

3187 <p
>Another issue I see is that we (as Debian Edu developers) should
3188 find out more about the network of people who do the marketing for
3189 Debian Edu / Skolelinux. There is a very active group in Germany
3190 promoting Skolelinux on the bigger Linux Days within Germany. Are
3191 there other groups like that in other countries? How can we bring
3192 these marketing people together (marketing group A with group B and
3193 all of them with the group of Debian Edu developers)? During the last
3194 meeting of the German Skolelinux group, I got the impression of people
3195 there being rather disconnected from the development department of
3196 Debian Edu / Skolelinux.

3241 <p

>Who are you, and how do you spend your days?

3243 <p
>I am a teacher from Germany, and my subjects are Geography,
3244 Mathematics, and Computer Science (
"Informatik
"). During the past
12
3245 years (since
2000), I have been working for a comprehensive (and soon,
3246 also inclusive) school leading to all kind of general levels, such as
3247 O- or A-level (
"Abitur
"). For quite as long, I
've been taking care of
3248 our computer network.
</p
>
3250 <p
>Now, in my early
40s, I enjoy the privilege of spending a lot of my
3251 spare time together with my wife, our son (
3 years) and our daughter
3252 (
4 months).
</p
>
3254 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3255 project?
</strong
></p
>
3257 <p
>We had tried different Linux based school servers, when members of
3258 my local Linux User Group (LUG OWL) detected Skolelinux. I remember
3259 very well, being part of a party celebrating the Linux New Media Award
3260 (
"Best Newcomer Distribution
", also nominated: Ubuntu) that was given
3261 to Skolelinux at Linux World Exposition in Frankfurt,
2005 (IIRC). Few
3262 months later, I had the chance to join a developer meeting in Ulsrud
3263 (Oslo) and to hand out the award to Knut Yrvin and others. For more
3264 than
7 years, Skolelinux is part of our schools infrastructure, namely
3265 our main server (tjener), one LTSP (today without thin clients), and
3266 approximately
50 work stations. Most of these have the option to boot a
3267 locally installed Skolelinux image. As a consequence, I joined quite
3268 a few events dealing with free software or Linux, and met many Debian
3269 (Edu) developers. All of them seemed quite nice and competent to me,
3270 one more reason to stick to Skolelinux.
</p

3272 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3273 Edu?
</strong
></p
>
3275 <p
>Debian driven, you are given all the advantages of a community
3276 project including well maintained updates. Once, you are familiar with
3277 the network layout, you can easily roll out an entire educational
3278 computer infrastructure, from just one installation media. As only
3279 free software (FOSS) is used, that supports even elderly hardware,
3280 up-sizing your IT equipment is only limited by space (i.e. available
3281 labs). Especially if you run a LTSP thin client server, your
3282 administration costs tend towards zero.
</p
>
3284 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3285 Edu?
</strong
></p
>
3287 <p
>While Debian
's stability has loads of advantages for servers, this
3288 might be different in some cases for clients: Schools with unlimited
3289 budget might buy new hardware with components that are not yet
3290 supported by Debian stable, or wish to use more recent versions of
3291 office packages or desktop environments. These schools have the
3292 option to run Debian testing or other distributions - if they have the
3293 capacity to do so. Another issue is that Debian release cycles
3294 include a wide range of changes; therefor a high percentage of human
3295 power seems to be absorbed by just keeping the features of Skolelinux
3296 within the new setting of the version to come. During this process,
3297 the cogs of Debian Edu are getting more and more professional,
3298 i.e. harder to understand for novices.
</p

3300 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3302 <p
>LibreOffice, Wikipedia, Openstreetmap, Iceweasel (Mozilla Firefox),
3303 KMail, Gimp, Inkscape - and of course the Linux Kernel (not only on
3304 PC, Laptop, Mobile, but also our SAT receiver)
</p

3306 <p
><strong
>Which strategy do you believe is the right one to use to
3307 get schools to use free software?
</strong
></p
>
3311 <li
>Support computer science as regular subject in schools to make
3312 people really
"own
" their hardware, to make them understand the
3313 difference between proprietary software products, and free software
3314 developing.
</li
>
3316 <li
>Make budget baskets corresponding: In Germany
's public schools
3317 there are more or less fixed budgets for IT equipment (including
3318 licenses), so schools won
't benefit from any savings here. This
3319 privilege is left to private schools which have consequently a large
3320 share among German Skolelinux schools.
</li
>
3322 <li
>Get free software in the seminars where would-be teachers are
3323 trained. In many cases, teachers
' software customs are respected by
3324 decision makers rather than the expertise of any IT experts.
</li
>
3326 <li
>Don
't limit ourself to free software run natively. Everybody uses
3327 free software or free licenses (for instance Wikipedia), and this
3328 general concept should get expanded to free educational content to be
3329 shared world wide (school books e.g.).
</li
>
3331 <li
>Make clear where ever you can that the market share of free (libre)
3332 office suites is much above
20 p.c. today, and that you pupils don
't
3333 need to know the
"ribbon menu
" in order to get employed.
</li
>
3335 <li
>Talk about the difference between freeware and free software.
</li
>
3337 <li
>Spread free software, or even collections of portable free apps
3338 for USB pen drives. Endorse students to get a legal copy of
3339 Libreoffice rather than accepting them to use illegal serials. And
3340 keep sending documents in ODF formats.

3359 gledelig overrasket da han dukket opp i Skolelinux-prosjektet etter å
3360 ikke ha sett noe til ham på mange år.

3362 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p

3364 <p
>Jeg er utdannet kokk av yrke, og har utøvet yrket i
12 år. Men
3365 etter at ryggen sa takk før seg, studerte jeg nettverksadministrasjon
3366 ved Næringsakademiet i Bergen årene
2008-
2009 slik at jeg kunne
3367 forfølge en av mine største interesser - data. Til daglig jobber jeg
3368 ved
<a href=

3369 ungdomsskole
</a
> med å drifte skolens PC-er. Har også litt

</p
>
3372 <p
>Mitt mål er å bevisstgjøre musikklærene mulighetene med de frie
3373 programmene som finnes i Skolelinux, blant annet Rosegarden.
</p
>
3375 <p
>Har i mange år drevet med musikk og en av grunnen til at Rosegarden
3376 falt i smak for min del, var fordi denne fungere og ligner mest på
3377 Windows-programmet (cubase) jeg jobbet mye med da jeg i mine yngre
3378 dager var «Windows fanatiker». Ble introdusert til Linux av en kompis
3379 av meg for omtrent
14 år siden, og har bare blitt mer og mer glad i
3380 dette operativsystemet.
</p
>
3382 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
3384 <p
>Da jeg ble sykemeldt fra min gamle jobb, og måtte omskoleres,
3385 havnet jeg i
2007 sammen med Viggo Fedreheim på IKT-avdelingen i
3386 Narvik kommune, der ble jeg for første gang introdusert til
3387 Skolelinuxprosjektet.
</p
>
3389 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
3391 <p
>Skolelinux er enkelt å holde i drift og masse flotte programmer som
3392 geogebra, ktouch og kgeografi følger med pakken. Man kan ta i bruk
3393 gamle PC-er igjen, slik at skoler med dårlig råd får opp en brukbar
3394 PC-park. PC-er som er ca
6-
9 år gamle fungere tilfredstillende, bare
3395 de har
512 MB RAM eller mer.
</p
>
3397 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
3399 <p
>Ulempene er at noen av de pedagogiske programmene som lærene ønsker
3400 å bruke fungere dårlig med Linux. Mye pga. av at disse programmene
3401 blir ikke laget til Linuxbaserte operativsystemer.
</p
>
3403 <p
>Video- og bilde-redigering har dessverre en del mangler, mange av
3404 programmene har en tendens til og krasje. Det gjelder blant annet
3405 <a href=
"http://www.kdenlive.org/
">kdenlive
</a
> og
3406 <a href=
"http://www.openshotvideo.com/
">openshot
</a
>, for å nevne
3407 noen. De er ikke stabile nok. Når elevene kommer med filmsnutter de
3408 ønsker og jobbe med, så godtar ikke programmene filene, og når elevene
3409 jobber med redigering bare krasjer programmene uten forvarsel. Det er
3410 for vanskelig å få noe som bare fungerer ut av boksen her. Når en elev
3411 plugger inn et videokamera eller fotoapparat så er det alltid noe som
3412 ikke vil fungere. Programmene godtar ikke format, godtar ikke
3413 kameraet, osv., osv. Det er dessverre med på og dra ned en positiv
3414 opplevelse av bruk av fri programvare.
</p
>
3416 <p
>Man må ofte bruke flere en et video redigerings program før og få
3417 fullført en ønsket oppgave.
</p
>
3419 <p
>Eksempel:
</p
>
3421 <p
>Hvis det ene programmet ikke vil ta i mot videofilen klarer et
3422 annet det, men det programmet som klarer det kan ikke gjøre de samme
3423 oppgavene som det programmet som ikke ville ta i mot filen,
3424 Tilsvarende er det med foto, man må bruke flere programmer for å få
3425 et ferdig resultat. Til dags dato har jeg enda ikke funnet et video-
3426 og fotoprogram som kan tilfredstillende fullføre en oppgave.
</p
>
3428 <p
>Så man kan klare og fullføre en oppgave, men i verste fall må man
3429 innom
3-
4 programmer for å få det til. Så jeg har enda ikke til dags
3430 dato sett at et program fungere
100% til alt.
</p
>
3432 <p
>Det programmet jeg har best erfaring til er
3433 <a href=
"http://cinelerra.org/
">cinelerra
</a
>, men dessverre har det
3434 også tendenser og krasje av og til uten grunn.
</p
>
3436 Lydsystemet kan også være et mareritt. Konkret snakker jeg om når du
3437 bruker for eksempel et smartboard, så følger det med USB-lydkort på
3438 disse. Problemet ligger her i at systemet ikke vil velge rett
3439 lydkort, så man må inn med padevchooser for å sette opp PulseAudio
3440 til og velge at USB-lydkortet skal brukes. Det blir for tungvindt for
3441 lærene, de ønsker at ting skal fungere med en gang. (min løsning på
3442 det problemet ble at jeg måtte deaktivere lydkortet som fantes på
3443 maskinen) men da må man bestandig slå på smartboard-tavla.
3445 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
3447 Programmene jeg bruker mest av er: Rosegarden, jack, qsynth, audacity,
3448 k3b, openttd og libreoffice.
3450 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
3451 skoler til å ta i bruk fri programvare?
</strong
></p
>
3453 Jeg tror det må bevisstgjøring av Skolene til, dvs. reklamere høylytt
3454 og fortelle og vise de andre skolene at frie programvarer faktisk
3455 fungere. Jeg trur faktisk mange ikke vet at det finnes frie

3466 publish another interview with the people behind
3467 <a href=

">Debian Edu and Skolelinux
</a
>.
3468 This time it is one of our German developers, who have helped out over the
3469 years to make sure both a lot of major but also a lot of the minor
3470 details get right before release.
3472 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3474 <p
>My name is Jürgen Leibner, I
'm
49 years old and living in
3475 Bielefeld, a town in northern Germany. I worked nearly
20 years as
3476 certified engineer in the department for plant design and layout of an
3477 international company for machinery and equipment. Since
2011 I
'm a
3478 certified technical writer (tekom e.V.) and doing technical
3479 documentations for a steam turbine manufacturer. From April this year
3480 I will manage the department of technical documentation at a
3481 manufacturer of automation and assembly line engineering.
</p
>
3483 <p
>My first contact with linux was around
1993. Since that time I used
3484 it at work and at home repeatedly but not exclusively as I do now at
3485 home since
2006.
</p
>
3487 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3488 project?
</strong
></p
>
3490 <p
>Once a day in the early year of
2001 when I wanted to fetch my
3491 daughter from primary school, there was a teacher sitting in the
3492 middle of
20 old computers trying to boot them and he failed. I helped
3493 him to get them booting. That was seen by the school director and she
3494 asked me if I would like to manage that the school gets all that old
3495 computers in use. I answered:
"Yes
".
</p
>
3497 <p
>Some weeks later every of the
10 classrooms had one computer
3498 running Windows98. I began to collect old computers and equipment as
3499 gifts and installed the first computer room with a peer-to-peer
3500 network. I did my work at school without being payed in my spare time
3501 and with a lot of fun. About one year later the school was connected
3502 to Internet and a local area network was installed in the school
3503 building. That was the time to have a server and I knew it must be a
3504 Linux server to be able to fulfil all the wishes of the teachers and
3505 being able to do this in a transparent and economic way, without extra
3506 costs for things like licence and software. So I searched for a
3507 school server system running under Linux and I found a couple of
3508 people nearby who founded
'skolelinux.de
'. It was the Skolelinux
3509 prerelease
32 I first tried out for being used at the school. I
3510 managed the IT of that school until the municipal authority took over
3511 the IT management and centralised the services for all schools in
3512 Bielefeld in December of
2006.

>What do you see as the advantages of Skolelinux/Debian
3515 Edu?

3517 <p
>When I
'm looking back to the beginning, there were other advantages
3518 for me as today.
</p
>
3520 <p
>In the past there were advantages like:
</p
>
3524 <li
>I don
't need to buy it so it generates no costs to the school as
3525 they had little money to spent for computers and software.
</li
>
3527 <li
>It has a licence which grands all rights to use it without
3530 <li
>It was more able to fit all requirements of a server system for
3531 schools than a Microsoft server system, even if there are only Windows
3532 clients because of it
's preconfigured overall concept of being a
3533 infrastructure solution and community for schools, not only a

>I was able to configure the server to the needs of the
3539 </ul

>
3541 <p
>Today some of the advantages has been lost, changed or new ones
3542 came up in this way:
</p
>
3546 <li
>Most schools here do have money to buy hardware and software
3549 <li
>They are today mostly managed from central IT departments which
3550 have own concepts which often do not fit to Debian Edu concepts
3551 because they are to close to Microsoft ideology.
</li
>
3553 <li
>With the Squeeze version of Debian Edu which now uses GOsa² for
3554 management I feel more able to manage the daily tasks than with the
3555 interfaces used in the past.
</li
>
3557 <li
>It is more modular than in the past and fits even better to the
3558 different needs.
</li
>
3560 <li
>The documentation is usable and gets better every day.
</li
>
3562 <li
>More people than ever before are using Debian Edu all over the
3563 world and so the community, which is an very important part I think,
3564 is sharing knowledge and minds.
</li

3566 <li
>Most, maybe all, of the technical requirements for schools are
3567 solved today by Debian Edu.

3576 <li
>There are too few IT companies able to integrate Debian Edu into
3577 their product portfolio for serving schools with concepts or even
3578 whole municipality areas.

3580 <li
>Debian Edu has beside other free and open software projects not
3581 enough lobbyists which promote free and open software to

3592 use on my laptop and my desktop are Open/Libre-office, Iceweasel,
3593 KMail, DigiKam, Amarok, Dolphin, okular and all the other programs I
3594 need from the KDE environment. On console I use newsbeuter, mutt,
3595 screen, irssi and all the other famous and useful tools.
</p

3597 <p
>My home server provides mail services with exim, dovecot, roundcube
3598 and mutt over ssh on the console, file services with samba, NFS,
3599 rsync, web services with apache, moinmoin-wiki, multimedia services
3600 with gallery2 and mediatomb and database services with MySQL for me

>Da jeg googlet etter noe annet kom jeg tilfeldigvis over
3618 <a href=
"http://www.duo.uio.no/sok/work.html?WORKID=
58309">en
3619 hovedfagsoppgave
</a
> ved Universitetet i Oslo som diskuterer verdien
3620 av GPLs fire friheter for brukerne av IT-systemer. Jeg ble fascinert
3621 over det som presenteres der. Her er sammendraget:
</p
>
3623 <p
><blockquote
>
3625 <p
>Motivasjonen til å skrive denne oppgaven er en personlig undring
3626 over hvorfor det primært, og ofte eksklusivt, fokuseres på det
3627 økonomiske aspektet ved utredninger om fri programvare er et godt valg
3628 for det offentlige. Fri og produsenteid programvare bygger på
3629 fundamentalt forskjellige ideologier som kan ha implikasjoner utover
3630 økonomiske kostnader. Kunnskapskulturen som er med på å definere fri
3631 programvare er basert på åpenhet, og er en verdi i seg selv.
</p
>
3633 <p
>Oppgavens tema er programvarelisensen GPL og frihet. GPL-lisensiert
3634 programvare gir visse friheter i forhold til produsenteid
3635 programvare. Mitt spørsmål er om, og eventuelt i hvilken utstrekning,
3636 disse frihetene blir benyttet av ulike brukere og hvordan de
3637 manifesterer seg for disse brukerne. Sentrale spørsmål i oppgaven
3641 <li
>Hvordan fordeles handlekraft gjennom lisensieringen av programvaren?
</li
>
3642 <li
>Hvilke konsekvenser har programvarelisensen for de ulike brukere?
</li
>
3645 <p
>Fri programvare gir blant annet brukeren mulighet til å studere og
3646 modifisere kildekoden. Denne formen for frihet erverves gjennom
3647 kunnskap og krever at brukeren også er en ekspert. Hva skjer med
3648 frihetene til GPL når sluttbrukeren er en annen? Dette diskuteres i
3649 dialog med informantene.
</p
>
3651 <p
>Jeg har i denne oppgaven samlet inn intervjudata fra IKT-ansvarlige
3652 ved grunnskolene i Nittedal kommune, driftsansvarlig og IKT-veilederen
3653 for skolene i kommunen, samt IKT-koordinator for utdanning i Akershus
3654 fylkeskommune og bokmåloversettere av OpenOffice.org. Den empiriske
3655 delen av oppgaven er delt inn i to seksjoner; den første omhandler
3656 operativsystemet Skolelinux, den andre kontorprogrampakken
3657 OpenOffice.org.
</p
>
3659 <p
>Som vi vil se gir GPL lokal frihet og kontroll gjennom omfordeling
3660 av makt fra produsent til bruker. Brukerens makt analyseres gjennom
3661 begrepene brukermedvirkning og handlingsfrihet. Det blir også lagt
3662 vekt på strukturelle forhold rundt bruken av teknologi, og spesielt de
3663 økonomiske begrepene nettverkseksternaliteter, innlåsing og
3664 stiavhengighet. Dette er begreper av spesiell nytte når objektet som
3665 omsettes eller distribueres er et kommunikasjonsprodukt, fordi verdien
3666 til et slikt gode for en potensiell bruker avhenger av antall
3667 eksisterende brukere av godet. I tilknytning til denne problematikken
3668 inneholder oppgaven også en diskusjon rundt åpne standarder og
3671 <p
>Oppgaven konkluderer med at de «fire frihetene» som GPL-lisensen er
3672 laget for å beskytte er av avgjørende betydning for bruken av
3673 OpenOffice.org og Skolelinux, i Akershus fylkeskommune såvel som i
3674 skolene i Nittedal. Distribusjonen av handlekraft er ikke helt
3675 symmetrisk. Det er først og fremst de profesjonelle utviklerne i
3676 Skolelinux som direkte kan nyttiggjøre seg friheten til å endre kode,
3677 mens en sluttbruker som Nittedal kommune nyttiggjør seg den økonomiske
3678 friheten til å kunne distribuere programmene. Det er imidlertid også
3679 slik at ingen aktør klarer seg uten alle disse «frihetene».

>Behind
<a href=
"http://www.skolelinux.org/
">Debian Edu and
3696 Skolelinux
</a
> there are a lot of people doing the hard work of
3697 setting together all the pieces. This time I present to you Andreas
3698 Mundt, who have been part of the technical development team several
3699 years. He was also a key contributor in getting GOsa and Kerberos set
3700 up in the recently released
3701 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">Debian
3702 Edu Squeeze
</a
> version.
</p
>
3704 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
3706 <p
>My name is Andreas Mundt, I grew up in south Germany. After
3707 studying Physics I spent several years at university doing research in
3708 Quantum Optics. After that I worked some years in an optics company.
3709 Finally I decided to turn over a new leaf in my life and started
3710 teaching
10 to
19 years old kids at school. I teach math, physics,
3711 information technology and science/technology.
</p
>
3713 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
3714 project?
</strong
></p
>
3716 <p
>Already before I switched to teaching, I followed the Debian Edu
3717 project because of my interest in education and Debian. Within the
3718 qualification/training period for the teaching, I started
3719 contributing.
</p
>
3721 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
3722 Edu?
</strong
></p
>
3724 <p
>The advantages of Debian Edu are the well known name, the
3725 out-of-the-box philosophy and of course the great free software of the
3726 Debian Project!
</p
>
3728 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
3729 Edu?
</strong
></p
>
3731 <p
>As every coin has two sides, the out-of-the-box philosophy has its
3732 downside, too. In my opinion, it is hard to modify and tweak the
3733 setup, if you need or want that. Further more, it is not easily
3734 possible to upgrade the system to a new release. It takes much too
3735 long after a Debian release to prepare the -Edu release, perhaps
3736 because the number of developers working on the core of the code is
3737 rather small and often busy elsewhere.
</p
>
3739 <p
>The
<a href=
"http://wiki.debian.org/DebianLAN
">Debian LAN
</a
>
3740 project might fill the use case of a more flexible system.
</p
>
3742 <p
><strong
>Which free software do you use daily?
</strong
></p
>
3744 <p
>I am only using non-free software if I am forced to and run Debian
3745 on all my machines. For documents I prefer LaTeX and PGF/TikZ, then
3746 mutt and iceweasel for email respectively web browsing. At school I
3747 have Arduino and Fritzing in use for a micro controller project.
</p
>
3749 <p
><strong
>Which strategy do you believe is the right one to use to
3750 get schools to use free software?
</strong
></p
>
3752 <p
>One of the major problems is the vendor lock-in from top to bottom:
3753 Especially in combination with ignorant government employees and
3754 politicians, this works out great for the
"market-leader
". The school
3755 administration here in Baden-Wuerttemberg is occupied by that vendor.
3756 Documents have to be prepared in non-free, proprietary formats. Even
3757 free browsers do not work for the school administration. Publishers
3758 of school books provide software only for proprietary platforms.
</p
>
3760 <p
>To change this, political work is very important. Parts of the
3761 political spectrum have become aware of the problem in the last years.
3762 However it takes quite some time and courageous politicians to
'free
'
3763 the system. There is currently some discussion about
"Open Data
" and
3764 "Free/Open Standards
". I am not sure if all the involved parties have
3765 a clue about the potential of these ideas, and probably only a
3766 fraction takes them seriously. However it might slowly make free
3767 software and the philosophy behind it more known and popular.

3834 <a href=

">Skolelinux Drift AS
</a
> on speeding
3835 up a
<a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>
3836 Lenny installation using LTSP diskless workstations, and in the
3837 process I discovered something very surprising. The reason the KDE
3838 menu was responding slow when using it for the first time, was mostly
3839 due to the way KDE find application icons. I discovered that showing
3840 the Multimedia menu would cause more than
20 000 IP packages to be
3841 passed between the LTSP client and the NFS server. Most of these were
3843 NFS LOOKUP calls, resulting in a NFS3ERR_NOENT response. Because the
3844 ping times between the client and the server were in the range
2-
20
3845 ms, the menus would be very slow. Looking at the strace of kicker in
3846 Lenny (or plasma-desktop i Squeeze - same problem there), I see that
3847 the source of these NFS calls are access(
2) system calls for
3848 non-existing files. KDE can do hundreds of access(
2) calls to find
3849 one icon file. In my example, just finding the mplayer icon required
3850 around
230 access(
2) calls.
</p
>
3852 <p
>The KDE code seem to search for icons using a list of icon
3853 directories, and the list of possible directories is large. In
3854 (almost) each directory, it look for files ending in .png, .svgz, .svg
3855 and .xpm. The result is a very slow KDE menu when /usr/ is NFS
3856 mounted. Showing a single sub menu may result in thousands of NFS
3857 requests. I am not the first one to discover this. I found a
3858 <a href=
"https://bugs.kde.org/show_bug.cgi?id=
211416">KDE bug report
3859 from
2009</a
> about this problem, and it is still unsolved.
</p
>
3861 <p
>My solution to speed up the KDE menu was to create a package
3862 kde-icon-cache that upon installation will look at all .desktop files
3863 used to generate the KDE menu, find their icons, search the icon paths
3864 for the file that KDE will end up finding at run time, and copying the
3865 icon file to /var/lib/kde-icon-cache/. Finally, I add symlinks to
3866 these icon files in one of the first directories where KDE will look
3867 for them. This cut down the number of file accesses required to find
3868 one icon from several hundred to less than
5, and make the KDE menu
3869 almost instantaneous. I
'm not quite sure where to make the package
3870 publicly available, so for now it is only available on request.
</p
>
3872 <p
>The bug report mention that this do not only affect the KDE menu
3873 and icon handling, but also the login process. Not quite sure how to
3874 speed up that part without replacing NFS with for example NBD, and
3875 that is not really an option at the moment.

1981 I

</strong

3928 <p
>The first information about Skolelinux must have come to my
3929 attention years ago and somehow related to LTSP (Linux Terminal Server
3930 Project). At school, we had set up a network at the beginning of
1997
3931 using Suse Linux on the desktop, replacing a Novell network. Since
3932 2002, we used old machines from the city council of Dortmund as thin
3933 clients (LTSP, later Ubuntu/Lessdisks) cause new hardware was out of
3934 reach. At home I
'm using Debian since years and - subscribed to the
3935 Debian news letter - heard from time to time about Skolelinux. About
3936 two years ago I proposed to replace the (somehow undocumented and only
3937 known to me) system at school by a well known Debian based system:
3938 Skolelinux.
</p
>
3940 <p
>Students and teachers appreciated the new system because of a
3941 better look and feel and an enhanced access to local media on thin
3942 clients. The possibility to alter and/or reset passwords using a GUI
3943 was welcomed, too. Being able to do administrative tasks using a GUI
3944 and to easily set up workstations using PXE was of very high value for
3945 the admin teachers.

's open source, easy to set up, stable and flexible due to it
's
3951 Debian base. It integrates LTSP out-of-the-box. And it is documented!
3952 So it was a perfect choice.
</p
>
3954 <p
>Being open source, there are no license problems and so it
's
3955 possible to point teachers and students to programs like
3956 OpenOffice.org, ViewYourMind (mind mapping) and The Gimp. It
's of
3957 high value to be able to adapt parts of the system to special needs of
3958 a school and to choose where to get support for this.

2011 som er laget på oppdrag fra
3997 Kunnskapsdepartementet. Dette har ført til debatt om PC-tilgangen i
3998 skolen, og om de med Linux i skolen gjør det bedre bedre eller
3999 dårligere enn snittet i landet.
</p

4001 <p
>Nå har vi tallene. Skoler med Linux har
36% større PC-tetthet en
4002 landsgjennomsnittet. På spørsmål hvorfor skoler med Linux har større
4003 PC-tetthet, observerer Paul Reidar Løsnesløkken som er IKT-konsulent i
4004 Nord-Odal:

4006 <p
><blockquote
>"Vi erfarer at klienter med Skolelinux har god funksjon
4007 til de er
8 til
10 år gamle. Dette er omtrent dobbelt så lenge som
4008 andre løsninger, og skolene får mer datautstyr for
4009 pengene.
"</blockquote
></p
>
4011 <p
>Undersøkelsen baserer seg på
56 skoler som har gjort det offentlig
4012 at de kjører Skolelinux eller annen Linux-utgave. De kan også ha PC-er
4013 med Windows i skolenettet. Når en sammenligner PC-tetthetene på
4014 skolene i kommunene Flora, Harstad, Kongsvinger, Narvik, Nittedal,
4015 Nord-Odal og Randaberg, er det i snitt
2,
28 elev pr. PC på skolene med
4016 Linux. På landsbasis er det
3.11 elev per PC i grunnskolen, i følge
4017 side
95 i Monitor-rapporten for
2011. Målingen viser dermed
36% større
4018 PC-tetthet i skoler med Linux.

>Skolelinux har til hensikt å gi alle barn full tilgang til
4023 skoleaktuelle dataprogram på sitt eget morsmål. Derfor følger det med
4024 godt over
100 skoleaktuelle programmene laget for læring. De fleste
4025 programmene er oversatt til over
50 språk. Elevene skal også kunne
4026 studere alle sider av dataprogrammene. Derfor følger også kildekode
4027 med. Elever med interesse kan lære av eksperter som har laget
4028 systemet. Dette med enkelt programmering i læreprogram som KTurtle,
4029 til profesjonelle verktøy som Qt Creator eller Java.
</p

4031 <p
>Skolelinux er laget for sentralisert drift, der alt teknisk
4032 administrasjon av alle skolene kan gjøres sentralt fra kommunehuset
4033 eller sentralt i en region. F.eks. drifter to-tre personer
70.000
4034 skoledatamaskiner på
200 skoler i delstaten Extremadura i
4035 Spania. Etter velykket bruk av Debian Edu i skolen, legger delstaten
4036 over til Debian på
40.000 datamaskiner i administrasjonen. Det er idag
4037 mange selskap som tilbyr profesjonell støtte til innføring og drift i
4038 Norge og verden.

4075 <description><p
>I serien med intervjuer av folk i
4076 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, får vi
4077 denne gangen høre fra en IKT-ansvarlig som har brukt Skolelinux i
4078 mange år, og vært storfornøyd med erfaringene så langt.
</p
>
4080 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
4082 <p
>Mitt navn er Roy-Arne Myhre og jeg er
42 år. Jeg er ansatt hos
4083 <a href=
"http://www.sandskole.no/
">Sand skole
</a
> (Balsfjord kommune)
4084 og har stort sett vært det siden
1990. Jeg er IKT ansvarlig ved
4085 skolen i
40% stilling –
10% undervisning – musikk.
</p
>
4087 <p
>Ved skolen er det ca
100 elever og ca
18 lærere +
4 assistenter i
4088 hele og delte stillinger. Alle lærerne har bærbar PC (dessverre med
4089 Win Vista) – assistenter har tilgang til egne. Vi benytter Fronter i
4090 det daglige arbeidet. Vi har ca
90 elevmaskiner som fungerer til
4091 daglig opp mot Linux server (XFCE) som driftes av
4092 <a href=
"http://www.bzz.no/
">BzzWare AS
</a
> via nett. Maskinparken
4093 består kun av brukt utstyr for elevene – og noe av dette begynner å
4094 bli vel gammelt selv som halvtykke klienter.
</p
>
4096 <p
><strong
>Hvordan kom du i kontakt med
4097 Skolelinux-prosjektet?
</strong
></p
>
4099 <p
>Vi kom første gang i kontakt med Skolelinux rundt
1997. Den gang
4100 var det oppstart-disketter i hver maskin, ikke mulighet for lyd og
4101 video, gamle nettverkskort og mye plundring. Vi hadde en ihuga
4102 forelder med som pådriver, forsker og inspirator for hele opplegget.
4103 Selv ante jeg knapt at Skolelinux fantes, men han var av den
4104 utforskende typen, og fikk både meg og skolelederen i trua på at dette
4105 var ting som kunne fungere. Etter dette har det gått gradvis
4106 framover; flere maskiner er hentet inn gjennom bl.a
4107 <a href=
"http://www.greentech.no/
">Greentech
</a
> og utrangert utstyr
4108 fra høgskole / Avinor og private givere. Når maskinene ble for trege
4109 for nye Windows-versjoner, sto vi klare til å putte dem i nettverket
4110 vårt. Dette betyr at vi i dag har
1:
1 dekning av maskiner på
4111 ungdomstrinnet og bedre enn
1:
2 på barnetrinnet. Dette er vi veldig
4112 fornøyd med, og vi kan ikke se for oss hverdagen som ville vært
4113 alternativet ved bruk av Windows med sine lisenser pr. Bruker/maskin.
4114 Da ville vi nok vært tilbake til
1-
2 maskiner pr klasserom med de
4115 negative konsekvenser det ville hatt for undervisningsformene våre. Vi
4116 kan ha en hel klasse i prosjektjobbing eller individuell jobbing
4117 samtidig – vi kan avholde tentamen og eksamen uten
4118 logistikkproblemer.
</p
>
4120 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4122 Hvor skal jeg begynne... Stabiliteten er et nøkkelord - det bare
4123 virker. Har du først fått en server med Skolelinux opp og gå, så må
4124 det en maskinarefeil eller sabotasje til for å stoppe den. Det at man
4125 kan bruke eldre maskiner som normalt sett ville gått på dynga, er også
4126 glimrende - billig for skoler med dårlig økonomi og bra for miljøet
4127 siden vi gjenbruker utstyr i stedet for å skaffe nytt. Vi ville aldri
4128 hatt mulighet til å operere med det maskinantallet vi har pr i dag
4129 hvis det ikke var for Skolelinux - så tilgjengelighet er et annet
4130 nøkkelord. Et tredje moment er sikkerhet og brukertilgang. Alle
4131 brukerer opererer med egne brukernavn og passord, samt egne
4132 brukerområder som kan tilpasses for både enbrukertilgang og for
4133 samarbeid med andre.
4135 Elever har godt av å se at det finnes andre alternativer enn de som
4136 storindustrien selger på lisensbasis - på den måten trenes de opp til
4137 å se flere muligheter og å foreta valg ut fra flere opsjoner.
4139 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4141 <p
>Ulempene med Skolelinux er nok utbredelsen og mangelen på kjennskap
4142 til dette i skolenorge. De som skal ta økonomiske avgjørelser rynker
4143 på nesen og vil gå for det kjente og «sikre» selv om det koster mye
4144 mer. Man får rett og slett litt hetta av å ikke kunne noe – og unngår
4145 dette for enhver pris.
</p
>
4147 <p
>I tillegg er mye av linux-systemet administrert av tekstkommandoer
4148 og er lite intuitiv/visuell for oss som ikke er «inne i»
4149 kildekodene». Så problemet er nok mye godt at de som
4150 utarbeider/drifter Skolelinux ikke helt klarer å sette seg ned på
4151 skoleadministratorens nivå når det gjelder problemer og
4152 utfordringer. Men dette er nok en utfordring alle administratorer
4153 sliter med uansett OS.
</p
>
4155 <p
>Derfor har vi valgt å støtte oss til BzzWare AS for assistanse i
4156 drifta slik at jeg har kunnet konsentrere meg mer om kabling, skifting
4157 av komponenter, veiledning av lærere og elever, vedlikehold av
4158 skrivere og annen daglig drift.
</p
>
4160 <p
>Elevene mestrer Skolelinux helt fint. Så lenge Internett
4161 (Iceweasel) og Libreoffice (Openoffice) fungerer er
90% av
4162 skolehverdagen velfungerende. I tillegg brukes jo en del av den
4163 pedagogiske programpakken bla. i forhold til matematikk og geografi,
4164 men det er såpass mye bra på nett om dagen, så disse programmene er
4165 mer som krydder å regne.
</p
>
4167 <p
>Jeg skulle ønske neste versjon av Skolelinux kunne komme litt
4168 mindre stappet med programmer, for halvparten blir aldri brukt, eller
4169 fungerer ikke uansett. Hva med et pedagogisk panel av lærere/IKT
4170 ansvarlige som kunne sagt: disse programmene skal være standard, så
4171 får resten være slike man kan legge til ved behov – det kan lett bli
4172 en jungel å bevege seg i.
</p
>
4174 <p
>Jeg ønsker meg også en mer grafisk versjon av
4175 <a href=
"http://bzz.no/lwat/trac/trac.cgi
">Lwat
</a
> hvor man kan krysse
4176 ut de som f.eks ikke skal ha internett-tilgang en dag pga
4177 eksamen/tentamen, samt en noe enklere brannmurløsning hvor man kan
4178 stenge for en del (få) sider på en enkel måte. Jeg liker godt
4179 Skolelinux sin ideologi om at filteret skal trenes i hodet på eleven –
4180 men av og til skulle jeg ønske at f.eks Facebook og Youtube kunne vært
4181 koblet vekk en periode for å få bedre utnyttelse av tid og
4182 ressurser. Disse to nettstedene er nok mye av årsaken til at mange
4183 lærere holder igjen databruken noe mer enn man kunne ønske.
</p
>
4185 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4187 Jeg benytter nesten bare fri programvare til daglig. LibreOffice,
4188 Iceweasel (Firefox), Thunderbird til e-post og Gimp til
4189 bildebehandling. Vi har PHP-Nuke-oppsatt hjemmeside. Det eneste som
4190 jeg ikke har fått helt til enda er videoredigering - her må man vel
4191 innrømme at Mac er hakket over, men da er vi igjen over på å se hva
4192 som egner seg best, og ta valg ut fra det. Folk flest lever i
4193 villfarelsen om at regneark HETER Excel og tekstbehandling HETER
4194 Word. Dette er en misforståelse som jeg bruker mye energi på å
4195 diskutere og
"åpne sinn
" på Microsoft-slaver. Dessverre er det mange
4196 IKT-ansvarlige som også har låst seg på at det eneste saliggjørende er
4197 Bill G sine produkter.
4199 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
4200 skoler til å ta i bruk fri programvare?
</strong
></p
>
4202 <p
>For å komme lenger i utbredelsen av Skolelinux tror jeg det må mer
4203 fram i nasjonale medier, samt komme bedre fram hva økonomien i dette
4204 valget vil være – samt mulighetene. Fri programvare er en berikelse og
4205 gjør oss i stand til å utføre arbeidet i skolen uten å måtte legge
4206 igjen tusener på tusener i Bill Gates lomme.. Få ETT nettsted med
4207 forståelig veiledning av installasjon/oppgradering og ETT forum med
4208 konkrete feilrettinger og problemer, så tror jeg vi kunne kommet et
4209 par skritt framover. Ellers tror jeg bare at ildsjelene må fortsette å
4210 skinne – kanskje flere enn oss følger etter på veien.

>Den siste uka har det vært en del skriverier om hvor store

"http://www.digi.no/

">oppslaget
4248 i Digi
</a
>. Diskusjonen fikk meg til å bli litt nysgjerrig på om
4249 Linux-skoler har større PC-tettet enn snittet i landet. Grunnlaget
4250 for diskusjonen har vært undersøkelsen
4251 <a href=
"https://iktsenteret.no/ressurser/monitor-
2011-skolens-digitale-tilstand
">Monitor
4252 2011</a
>, som bruker informasjon fra
4253 <a href=
"https://www.wis.no/gsi
">Grunnskolens Informasjonssystem
</a
>
4254 (GSI). GSI-data kan lastes ned fra web og jeg lastet ned en Excel-fil
4255 (intet åpen standard-valg tilgjengelig) med navn på alle skoler,
4256 hvilke kommune de befinner seg i og hvor mange elever pr. elev-PC de
4257 har rapportert inn. For å få en ide om svaret trenger jeg deretter å
4258 vite hvilke skoler i landet som bruker Linux, slik at jeg kan slå dem
4259 opp i GSI og finne ut hvor stor PC-tetthet de har.
</p
>
4261 <p
>Jeg vet om skoler i Balsfjord, Flora, Harstad, Kongsvinger, Narvik,
4262 Nittedal, Nord-Odal, Randaberg og Sunndal som bruker Skolelinux eller
4263 andre Linux-varianter. Jeg tror det er flere enn de
56 skolene jeg
4264 har klart å identifisere de siste dagene, men har ikke klart å få det
4265 bekreftet med offentlige kilder.
</p
>
4267 <p
>Monitor
2011-rapporteres side
95 forteller at det
"ifølge GSI
4268 (
20120-
2011) er det
3,
11 elever per datamaskin når vi tar med alle
4269 grunnskoler (
1.-
10.trinn)
". For de
56 Linux-skolene jeg har klart å
4270 koble mot informasjon i GSI er det
2,
28 elever per elevdatamaskin,
4271 hvilket betyr at det er
36% høyere PC-tetthet på Linux-skoler enn
4272 landsgjennomsnittet. Linux-skolen med høyest tettet blant de jeg har
4273 notert -skole er Flora ungdomsskule i Flora kommune med
0.82 elev
4274 pr. PC (
482 elever,
588 elevdatamaskiner).
</p
>
4276 <p
>Skolelinux gir datamaskiner lengre levetid, og en kan dermed få
4277 flere operative datamaskiner for samme budsjett, i tillegg til en
4278 rekke andre fordeler. Kan det være forklaringen på forskjellen?
</p
>
4280 <p
>Tallene må tas med en liten klype, da GSI ser ut til å ha endel
4281 feilføringer. Jeg synes i hvert fall en skole med
423 elever og
9
4282 elevmaskiner ser mistenkelig ut. Eller en skole med
346 elever,
0
4283 elevmaskiner, som er et annet ekstremt eksempel jeg fant.

4304 Langley, near London, UK. Previously I worked as a technical
4305 author/trainer while my children attended the school, and I also
4306 contributed to the Schoolforge UK community with the aim of
4307 encouraging UK schools to adopt free/open source software. Five or six
4308 years ago we had about
50 schools interested in some way, but we
4309 weren
't able to convert many of them into sustainable
4310 installations.

4315 <p
>Skolelinux had two representatives at an early Edubuntu meeting in
4316 London which I attended. However at that time our school network had
4317 just been installed using CentOS, LTSP
4 and GNOME. When LTSP
5 came
4318 along we switched to Edubuntu thin client servers so now we have a
4319 mixed environment which includes Windows PCs and student laptops, as
4320 well as their MacBooks and iPads. However, the proprietary systems
4321 have always been rather problematic, and we never built a GUI for the
4322 LDAP server, so when I discovered Skolelinux is configured for all
4323 these things we decided to try it.

4328 <p
>By far the biggest advantage is the Debian Edu community. Apart
4329 from that I have always believed in the same
"sustainable computing

4330 goals that Skolelinux is built on: installing Linux on computers which
4331 would otherwise be thrown away, to provide a reliable, secure and
4332 low-cost IT environment for schools. From my own experience I know
4333 that a part-time person can teach and manage a network of about
25
4334 Linux computers, but it would take much more of my time if we had
4335 proprietary software everywhere.

4357 <p

's a tough question! For very many years UK schools installed
4358 and taught only proprietary software, so that at the highest levels
4359 the notion of
"computer
" means simply
"proprietary office
4360 applications
". However, schools today are experiencing budget
4361 constraints, and many are having to think hard about upgrading Windows
4362 XP. At the same time, we have students showing teachers how to use
4363 iPads, MacBooks and Android, so the choice of operating system is no
4364 longer quite so automatic. What is more, our government at last
4365 realised that we need people with programming skills, so they
're
4366 putting coding back in the curriculum! And it
's encouraging that the
4367 first

000 Raspberry Pi units sold out in
2 hours.

4369 <p
>I don
't really know what strategy is going to get UK schools to use
4370 free software, but building an active community of Skolelinux/Debian
4371 Edu users in this country has to be part of it.

>Documentation in Debian Edu is provided in several languages, and
4381 it is important to make it both easy to contribute and to keep the
4382 translated versions in sync. To do this we have come up with what we
4383 believe is a very efficient work flow.
</p
>
4387 <li
>The documentation is written in a
4388 <a href=
"http://moinmo.in
">moinmoin wiki
</a
> (see for example
4389 <a href=
"http://wiki.debian.org/DebianEdu/Documentation/Squeeze
">the
4390 Squeeze release manual
</a
>) with support for exporting the content as
4391 docbook XML.
</li
>
4393 <li
>This docbook document is given to po4a to extract a gettext style
4394 .pot file with the content, which in turn is used to create .po files
4395 with the translated text.
</li
>
4397 <li
>The .po files are given to translators, and they can always tell
4398 which part of the original wiki document is new or changed. They can
4399 use their normal translation tools like lokalize or poedit to write
4400 the translation. There is even a system in place to handle translated
4403 <li
>The translated .po files are combined with the original docbook
4404 XML document using po4a to create a translated docbook document.
</li
>
4406 <li
>The final step is to use all the generated docbook files and
4407 create PDF and HTML version of the original and translated documents.
</li
>
4411 <p
>This setup work very well, but have a few issues. The biggest
4412 issue is that
<a href=
"http://moinmo.in/DocBook
">the docbook support
4413 we use in moinmoin
</a
> is not actively maintained. The docbook
4414 support is also buggy, and our build system contain workarounds to
4415 make sure the generated docbook is usable despite these bugs.

4474 <p
>Jeg hørte om det først når jeg jobbet i Redpill Linpro. Men jeg
4475 har også en datter som går på en friskole, som også bruker Skolelinux.
4476 Som kjent har ikke friskoler de samme økonomiske rammebetingelsene som
4477 offentlige skoler, så for dem var det det absolutt beste alternativet.
4478 De anser også Skolelinux som et stabilt system, som bare går og går (i
4479 motsetning til det lille Windows-baserte nettverket de har på
4480 admin-siden).

4484 <p
>Sentralisert drift av tynne og diskløse arbeidsstasjoner. Således
4485 lydløse og raskere arbeidsstasjoner som er bedre i klasserommet.
4486 Lengre levetid på PC
'er. Store besparelser på maskinvare og drift. Og
4487 så klart fjerning av alle lisenskostnader. Personlig synes jeg også at
4488 mange av programmene er bedre enn alternativene. Men dette er ofte en
4489 smakssak og avhengig om man må ha det man er vant til fra før.

4491 <p

>Hva er ulempene med Skolelinux slik du ser det?

4493 <p
>For lite kjentskap til løsningen. Noen ganger for dårlig
4494 kompatibilitet med arbeidsstasjoners/bærbare maskiner sine
4495 nettverksdrivere eller skjermkort. Men dette løser vi i skolene ved
4496 standardisering. Ellers er det få, om nesten ingen, av de kjente
4497 maskinvare / infrastruktur leverandørene til fylkes- / kommuner som
4498 tilbyr denne plattformen. Skal dette endre seg så må kommunene selv
4499 sette slike krav til leverandørene.

4501 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
4503 <p
>Har brukt OpenOffice.org siden starten (
2001 ?), Kun Linux på
4504 desktop siden
2005. Bruker i dag Kubuntu, Libreoffice og ymse annet
4505 programvare til ulik kontorbruk som er lett å installere / teste via
4506 alle programarkivene som finnes.

4508 <p

4509 skoler til å ta i bruk fri programvare?
</strong
></p
>
4511 <p
>Fortsette å presentere flere av de gode eksemplene hvor Debian Edu
4512 / Skolelinux brukes i kommuner og enkeltskoler. Vi må få bedre frem
4513 at det er mulig tilknytte både Windows og Mac klienter på denne
4514 plattformen (selv om det vil øke driftskostnadene). Dette gjøres
4515 mange steder. Spesielt er det mange lærere som ønsker å bruke
4516 Windows/Mac-bærbare, gjerne som sin private PC også. Det er også mulig
4517 for kommunen å integrere med Active Directory i stedet for OpenLDAP
4518 som kommer med ut av boksen (selv om også dette øker kostnadene).
4519 Dette vil muligens bidra til å fjerne noe motstand hos noen
4520 potensielle brukere / driftpersonell for å ta i bruk noe
4521 nytt. Fremveksten av mobile brukere og nettbrett går i vår favør.
4522 Brukerne blir kjent og vant til flere nye operativsystemer /
4523 brukergrensesnitt. Så utviklerfellesskapet bør jobbe videre med å
4524 integrere flere nye klienttyper, som ultra lav-kostklienter og
4525 nettbrett (blant annet fri programvare-alternativet

>Inspired by
<a href=
"http://raphaelhertzog.com/tag/interview/
">the
4557 interview series
</a
> conducted by Raphael, I started a Norwegian
4558 interview series with people involved in the Debian Edu / Skolelinux
4559 community. This was so popular that I believe it is time to move to a
4560 more international audience.
</p
>
4562 <p
>While
<a href=
"http://www.skolelinux.org/
">Debian Edu and
4563 Skolelinux
</a
> originated in France and Norway, and have most users in
4564 Europe, there are users all around the globe. One of those far away
4565 from me is Nigel Barker, a long time Debian Edu system administrator
4566 and contributor. It is thanks to him that Debian Edu is adjusted to
4567 work out of the box in Japan. I got him to answer a few questions,
4568 and am happy to share the response with you. :)
4571 <p
><strong
>Who are you, and how do you spend your days?
</strong
></p
>
4573 <p
>My name is Nigel Barker, and I am British. I am married to Yumiko,
4574 and we have three lovely children, aged
15,
14 and
4(!) I am the IT
4575 Coordinator at Hiroshima International School, Japan. I am also a
4576 teacher, and in fact I spend most of my day teaching Mathematics,
4577 Science, IT, and Chemistry. I was originally a Chemistry teacher, but
4578 I have always had an interest in computers. Another teacher teaches
4579 primary school IT, but apart from that I am the only computer person,
4580 so that means I am the network manager, technician and webmaster,
4581 also, and I help people with their computer problems. I teach python
4582 to beginners in an after-school club. I am way too busy, so I really
4583 appreciate the simplicity of Skolelinux.
</p
>
4585 <p
><strong
>How did you get in contact with the Skolelinux/Debian Edu
4586 project?
</strong
></p
>
4588 <p
>In around
2004 or
5 I discovered the ltsp project, and set up a
4589 server in the IT lab. I wanted some way to connect it to our central
4590 samba server, which I was also quite poor at configuring. I discovered
4591 Edubuntu when it came out, but it didn
't really improve my setup. I
4592 did various desperate searches for things like
"school Linux server
"
4593 and ended up in a document called
"Drift
" something or other. Reading
4594 there it became clear that Skolelinux was going to solve all my
4595 problems in one go. I was very excited, but apprehensive, because my
4596 previous attempts to install Debian had ended in failure (I used
4597 Mandrake for everything - ltsp, samba, apache, mail, ns...). I
4598 downloaded a beta version, had some problems, so subscribed to the
4599 Debian Edu list for help. I have remained subscribed ever since, and
4600 my school has run a Skolelinux network since Sarge.
</p

4602 <p
><strong
>What do you see as the advantages of Skolelinux/Debian
4603 Edu?
</strong
></p
>
4605 <p
>For me the integrated setup. This is not just the server, or the
4606 workstation, or the ltsp. Its all of them, and its all configured
4607 ready to go. I read somewhere in the early documentation that it is
4608 designed to be setup and managed by the Maths or Science teacher, who
4609 doesn
't necessarily know much about computers, in a small Norwegian
4610 school. That describes me perfectly if you replace Norway with
4613 <p
><strong
>What do you see as the disadvantages of Skolelinux/Debian
4614 Edu?
</strong
></p
>
4616 <p
>The desktop is fairly plain. If you compare it with Edubuntu, who
4617 have fun themes for children, or with distributions such as Mint, who
4618 make the desktop beautiful. They create a good impression on people
4619 who don
't need to understand how to use any of it, but who might be
4620 important to the school. School administrators or directors, for
4621 instance, or parents. Even kids. Debian itself usually has ugly
4622 default theme settings. It was my dream a few years back that some
4623 kind of integration would allow Edubuntu to do the desktop stuff and
4624 Debian Edu the servers, but now I realise how impossible that is. A
4625 second disadvantage is that if something goes wrong, or you need to
4626 customise something, then suddenly the level of expertise required
4627 multiplies. For example, backup wasn
't working properly in Lenny. It
4628 took me ages to learn how to set up my own server to do rsync backups.
4629 I am afraid of anything to do with ldap, but perhaps Gosa will
4632 <p
><strong
>Which free software do you use daily?
</strong
></p
>
4634 <p
>Nowadays I only use Debian on my personal computers. I have one for
4635 studio work (I play guitar and write songs), running AV Linux
4636 (customised Debian) a netbook running Squeeze, and a bigger laptop
4637 still running Skolelinux Lenny workstation. I have a Tjener in my
4638 house, that
's very useful for the family photos and music. At school
4639 the students only use Skolelinux. (Some teachers and the office still
4640 have windows). So that means we only use free software all day every
4641 day. Open office, The GIMP, Firefox/Iceweasel, VLC and Audacity are
4642 installed on every computer in school, irrespective of OS. We also
4643 have Koha on Debian for the library, and Apache, Moodle, b2evolution
4644 and Etomite on Debian for the www. The firewall is Untangle.
</p
>
4646 <p
><strong
>Which strategy do you believe is the right one to use to
4647 get schools to use free software?
</strong
></p
>
4649 <p
>Current trends are in our favour. Open source is big in industry,
4650 and ordinary people have heard of it. The spread of Android and the
4651 popularity of Apple have helped to weaken the impression that you have
4652 to have Microsoft on everything. People complain to me much less about
4653 file formats and Word than they did
5 years ago. The Edu aspect is
4654 also a selling point. This is all customised for schools. Where is the
4655 Windows-edu, or the Mac-edu? But of course the main attraction is
4656 budget.The trick is to convince people that the quality is not
4657 compromised when you stop paying and use free software instead. That
4658 is one reason why I say the desktop experience is a weakness. People
4659 are not impressed when their USB drive doesn
't work, or their browser
4660 doesn
't play flash, for example.

<a href=
"http://www.skolelinux.org/
">Skolelinux
4707 / Debian Edu project
</a
> initiated a student project to create a tool
4708 for making stop motion movies. The proposal came from a teacher
4709 needing such tool on Skolelinux. The project, called
"stopmotion
",
4710 was manned by two extraordinary students and won a school award and a
4711 national aware with this great project. The project was initiated and
4712 mentored by Herman Robak, and manned by the students Bjørn Erik Nilsen
4713 and Fredrik Berg Kjølstad. They got in touch with people at Aardman
4714 Animation studio and received feedback on how professionals would like
4715 such stopmotion tool to work, and the end result was and is used by
4716 animators around the globe. But as is usual after studying, both got
4717 jobs and went elsewhere, and did not have time to properly tend to the
4718 project, and it has been lingering for a few years now. Until last
4721 <p
>Last year some of the users got together with Herman, and moved the
4722 project to Sourceforge and in effect restarted the project under a new
4724 <a href=
"http://sourceforge.net/projects/linuxstopmotion/
">linuxstopmotion
</a
>.
4725 The name change was done to make it possible to find the project using
4726 Internet search engines (try to search for
'stopmotion
' to see what I
4727 mean). I
've been following
4728 <a href=
"https://lists.sourceforge.net/lists/listinfo/linuxstopmotion-community
">the
4729 mailing list
</a
> and the improvement already in place and planned for
4730 the future is encouraging. If you want to make stop motion movies.

4807 <p
>Knut Yrvin her. Jobber i Nokia med å fremme rammeverket Qt og QML
4808 med tilhørende utviklerverktøy. Rollen er som leder av
4809 friprog-samfunn. I fjor var jeg med å legge om utviklingen av Qt til
4810 åpen forvaltning. På den måten kan alle som bidrar til Qt gjøre det
4811 på like vilkår. Nå er det
4812 <a href=

5-%E2%
80%

">over
4813 1000 utviklere
</a
> som bidrar til Qt. Med overgangen til åpen
4814 forvaltning er utviklingen av Qt mer åpen enn Linux-kjernen.
</p
>
4816 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
4818 <p
>Jeg var en av initiativtagerne til Skolelinux i
2001. Skolene slet
4819 med både utstyr og Internett-tilgang. De klarte ikke å møte
4820 forventningene til data i skolen. Driften av PC-ene var uholdbar. Som
4821 regel hadde rektor pekt ut en ivrig lærer til å passe på PC-ene,
4822 gjerne naturfaglæreren. Mange lærere jobbet mye ubetalt overtid for å
4823 vedlikeholde
30-
40 datamaskiner på hver sin skole. Med
300 elever og
4824 lærere som brukere, blir det fort mye mer arbeid enn de
4-
8 timene de
4825 kunne bruke på PC-drift. Skolene hadde kun en femtedel av
4826 IT-budsjettet som ble brukt på PC-ene i rådhuset.
</p
>
4828 <p
>Vi erfarte at skolene hadde mye datautstyr som stod ubrukt. Skolene
4829 manglet penger til Microsoft-lisenser. Selv med solide skolerabatter,
4830 kostet Microsoft-lisensene gjerne like mye som PC-ene i seg selv over
4831 en periode på
5-
6 år.
</p
>
4833 <p
>Viktigheten av språklig mangfold og pedagogiske programmer var også
4834 viktig for oss. Vi oversatte mange skoleaktuelle programmer til
4835 nynorsk, nordsamisk og bokmål. Dette lenge før andre tok denne
4836 oppgaven seriøst. Allerede etter ett år hadde vi etablert et helt
4837 arsenal av skoleaktuelle programmer på nynorsk, bokmål og
4838 nordsamisk. Vi spredde vår ide om språklig mangfold til de andre frie
4839 prosjekter internasjonalt. Resultatene ser vi i mange land. Det er de
4840 frie programmene som kommer på brukernes morsmål. Det er en av flere
4841 gode grunner til at fri programvare som LibreOffice, VLC, KDE og
4842 Firefox konkurrerer ut godseid programvare mange steder i verden.
</p
>
4844 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
4846 <p
>Fordelene er at Skolelinux tilbyr over
100 skoleaktuelle programmer
4847 på de norske språkene, uten ett øre i lisenskostnader. Systemet gir
4848 enormt lave driftskostnader med diskløse arbeidsstasjoner og bærbare
4849 med roaming. Skolelinux krever også mindre av maskinvaren.
</p
>
4851 <p
>Man kan fint kjøre systemet med
512 MB RAM på en bærbar PC sammen
4852 med en nettvideo i nettleseren og en presentasjon med
4853 LibreOffice. Konkurrerende system krever fort
2 GB RAM for å få til
4854 noe tilsvarende uten at det går ufattelig tregt. Skal man gjøre noe
4855 nyttig, krever konkurrentene til Linux mye større harddisk. Skoler har
4856 rapportert at de fort har fått
50% flere nye maskiner om de velger
4857 Linux. Dette i tillegg til de årlige besparelsene ved å unngå
4858 lisensbetaling til godseid programvare.
</p
>
4860 <p
>De lave driftskostnadene gjør at delstater i Europa har titusener
4861 av datamaskiner med Skolelinux i skolen. F.eks. er det under ti
4862 personer som drifter
70.000 PC-systemer i skolene i Extremadura i
4863 Spania. Det er slett ikke uvanlig at norske kommuner har
1500-
2000
4864 datamaskiner med Skolelinux. Driften tar ett årsverk. Slår flere
4865 kommuner seg sammen, kan de få samme sentraliserte stordriftsfordeler
4866 som delstater i Tyskland og Spania. Delstater som kjører Skolelinux
4867 på alle skolene. Bare noen få personer sentraldrifter titusenvis av
4870 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
4872 <p
>Den største ulempen for Skolelinux er motstand mot Linux fra
4873 IT-sjefer i det offentlige. Dette er ledere som holder innlegg som
4874 snytt ut av evangelist-håndboka til Microsoft. Dette gjøres i ett
4875 arbeidsmarked med stor vekst i etterspørselen etter Linux-fagfolk i
4876 privat sektor. Etterspørselen har økt mer enn noe annet tekniske yrke
4877 siste tiåret. Åtte av ti ledere vil ansette Linux-fagfolk i
2012,
4878 rapporterer jobbnettstedet Dice.com på oppdrag av Linux
4879 Foundation.
</p
>
4881 <p
>Det mangler
16.000 ingeniører og IKT-fagfolk i Norge rapporterte
4882 arbeids- og velferdsetaten NAV. Linux-fagfolk kan velge svært
4883 interessante jobber med alt fra apps på ledende mobilsystem laget med
4884 Linux, sky- tjenester eller web-applikasjoner. De raskest voksende
4885 teknologiselskapene i verden er ute etter Linux-fagfolk. Det være seg
4886 Amazon, Google, Facebook og IBM for å nevne noen. Linux er kritisk
4887 for å sikre veksten i markedet. Det sier seg selv at lønningene og
4888 jobbmulighetene er bedre enn for andre tekniske yrker.
</p
>
4890 <p
>Skal man lage apps for mobilen, smart-TV-en eller
4891 underholdningssystemet i bilen eller på flyet, er det Linux som
4892 gjelder. Med en slik konkurranse om Linux-kompetansen, kombinert med
4893 motstanden mot Linux hos mange IT-sjefer i offentlig sektor, så
4894 hindrer kommunene rekruttering av flere Linux- fagfolk. Skolene blir
4895 tvunget til å velge dyrere og mindre komplette IT-system. De har
4896 blitt hengende igjen slik IT var på begynnelsen av
2000- tallet. Dette
4897 fordi IT-ledere ikke har tilpasset seg markedet det siste tiåret.
</p
>
4899 <p
>Når det er sagt, er Skolelinux svært enkelt å lære seg også for de
4900 som ikke kan. Det viser alle lærerne som drifter systemet for
4901 hundrevis og tusenvis av systemer. Det meste er på plass rett ut av
4902 boksen. I tillegg er det solid med dokumentasjon med god hjelp på
4903 nettet. Det er mange kommuner som har ansatt en lærer som først lærte
4904 Skolelinux på sin skole, for så å drifte alle PC-ene i kommunen med
4905 Skolelinux. Det kan fort være snakk om
1000-
3000 datamaskiner på
10-
15
4906 skoler som sentraldriftes med en stilling. Står man ordentlig fast,
4907 kan man også kjøpe profesjonell hjelp fra selskap som støtter
4908 Skolelinux. Det er flere slike selskap i Norge og i utlandet.

>Qt SDK, LibreOffice, Firefox, VLC og KDE-skrivebordet. Dette på et
4913 Debian-basert GNU/Linux-system. Jeg bruker også noen morsomme
4914 3D-spill. Idag kan jeg velge mellom over
30.000 Linux-programmer. Det
4915 finnes ikke tid i livet å undersøke alle valgmulighetene. Derfor er
4916 det bra med Skolelinux i skolen, da utvalget av programmer er
4917 begrenset til hva som er aktuelt i skolefagene.

><strong
>Hvilken strategi tror du er den rette å bruke for å få
4920 skoler til å ta i bruk fri programvare?
</strong

4922 <p
>Vi må selge hele Skolelinux forhåndsinstallert på maskinvare i hele
4923 pakker med
50-
100-
1000 PC-klienter med servere. Dette kan selges til
4924 enkeltskoler eller hele kommuner. Pakken må inneholde tjenermaskiner,
4925 svært rimelige diskløse arbeidsstasjoner, nettbrett med Plasma Active,
4926 og bærbare med roaming. Alt er godt testet med Debian. I et slikt
4927 anbud er det mulig å legge til sentraliserte drifts- og
4928 støttetjenester.
</p
>
4930 <p
>Man bør også selge sky-tjenester som læreadministrative systemet
4931 Moodle og driftsovervåking. I tillegg så bør man slenge seg på med
4932 presentasjoner de gangene LibreOffice og andre friprog-produkter
4933 selges til kommuner.

5010 gjennom studentprosjekter der elevene selv er med å utforme
5011 programvare direkte eller indirekte gjennom aktive bidrag. Dette gjør
5012 ikke bare samarbeidet tettere, men fokuset på standarder og friheten
5013 til å velge sin egen løsning vil kanskje stimulere interessen for
5014 framtidig deltakelse i bransjen. Vi som driver med fri og åpen
5015 programvare ønsker oss ikke rene konsumenter, men tenkende og

5069 is frozen. An alternative would be for us to rewrite wpad-extract to
5070 use some other javascript library currently working in Wheezy, but no
5071 known alternative is known at the moment.

>This automatic proxy system allow the roaming workstation (aka

5075 is connected to the backbone network in a Debian Edu setup, and to
5076 automatically use any proxy present and announced using the WPAD
5077 feature when it is connected to other networks. And if no proxy is
5078 announced, direct connections will be used instead.

>Silently using a proxy announced on the network might be a privacy
5081 or security problem. But those controlling DHCP and DNS on a network
5082 could just as easily set up a transparent proxy, and force all HTTP
5083 and FTP connections to use a proxy anyway, so I consider that
5084 distinction to be academic. If you are afraid of using the wrong
5085 proxy, you should avoid connecting to the network in question in the
5086 first place. In Debian Edu, the proxy setup is updated using dhcp and
5087 ifupdown hooks, to make sure the configuration is updated every time
5088 the network setup changes.

5114 <p
>Tror jeg så en annonsering på nettet i slutten av
2001 og ville
5115 være med som oversetter. Jeg kom med på en utviklersamling og
5116 prosjektet var da helt i starten. Det var spennende å være med mens
5117 prosjektet vokste til og utviklet seg.
</p

5119 <p
>Jeg har «alltid» vært språkinteressert og hadde nettopp startet med
5120 Linux og tror jeg tenkte det passet å bidra. Var også glad for å få
5121 en Debian-distribusjon, og ville gjerne bruke den selv. Til å begynne
5122 med brukte jeg først Mandrake og så Debian. Og siden jeg oppdaget at
5123 det ikke var noen mulighet for å bruke den som enkeltstående i lang
5124 tid, så gikk jeg etterhvert over til Kubuntu

5126 <p

>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

5128 <p
>Løsningen er forholdsvis lett å sette opp, gratis, fri programvare
5129 og gjør det mulig å gjenbruke eldre maskiner. Det fine med Debian er
5130 at det er stabilt og har en veldig stor mengde programmer. Jeg liker
5131 også apt. :-) Jeg liker også friheten ved Linux og muligheten til å
5132 delta og forme sin egen datahverdag.

5136 <p
>Skolelinux er for lite kjent og for sent ute med å gi ut nye
5137 versjoner.
</p
>
5139 <p
>Da jeg selv i hovedsak bruker Kubuntu, så kan jeg egentlig ikke
5140 svare så detaljert rundt ulempene med Skolelinux. Hovedårsaken til at
5141 jeg bruker Kubuntu er nok at da vi begynte med det mener jeg det ikke
5142 var noen annen løsning. «Vandrende arbeidsstasjon» mener jeg ikke
5143 fantes da. Dessuten ville jeg ha siste versjon, da den KDE-versjonen
5144 som var i Skolelinux den gangen var en god del enklere (tror det var
5145 KDE
2) var dårligere i mine øyne enn versjon
3.

5163 <p
>Det viktigste er å forankre beslutningen i kollegiet og med de som
5164 er ansvarlige for å vedlikeholde og bruke datamaskinene. Flest mulig
5165 bør være med på å holde det (sosialt) vedlike, kjenne og støtte
5166 prinsippene. Som enkeltmannsprosjekt blir det lett veldig sårbart,
5167 særlig når (Skole)linux ennå i stor grad er en motkultur og ikke noe
5168 en stor nok andel av beslutningstakere, brukere osv kjenner til og
5171 <p
>Jeg tror det viktigste er å fortsette å holde fri programvare godt,
5172 oppdatert, minimere antall feil, ha en god kontakt med brukerne og
5173 attraktivt og spennende programmer. Beholde alt som er bra og ha det
5174 tilgjengelig samtidig som man tilbyr det nyeste og rareste for de som
5175 vil ha det.

>Since the Lenny version of
5185 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
>, a
5186 feature to save power have been included. It is as simple as it is
5187 practical: Shut down unused clients at night, and turn them on again
5188 in the morning. This is done using the
5189 <a href=
"http://packages.qa.debian.org/s/shutdown-at-night.html
">shutdown-at-night
</a
> Debian package.
</p
>
5191 <p
>To enable this feature on a client, the machine need to be added to
5192 the netgroup shutdown-at-night-hosts. For Debian Edu, this is done in
5193 LDAP, and once this is in place, the machine in question will check
5194 every hour from
16:
00 until
06:
00 to see if the machine is unused, and
5195 shut it down if it is. If the hardware in question is supported by
5197 <a href=
"http://packages.qa.debian.org/n/nvram-wakeup.html
">nvram-wakeup
</a
>
5198 package, the BIOS is told to turn the machine back on around
07:
00 +-
5199 10 minutes. If this isn
't working, one can configure wake-on-lan to
5200 try to turn on the client. The wake-on-lan option is only documented
5201 and not enabled by default in Debian Edu.
</p
>
5203 <p
>It is important to not turn all machines on at once, as this can
5204 blow a fuse if several computers are connected to the same fuse like
5205 the common setup for a classroom. The nvram-wakeup method only work
5206 for machines with a functioning hardware/BIOS clock. I
've seen old
5207 machines where the BIOS battery were dead and the hardware clock were
5208 starting from
0 (or was it
1990?) every boot. If you have one of
5209 those, you have to turn on the computer manually.
</p
>
5211 <p
>The shutdown-at-night package is completely self contained, and can
5212 also be used outside the Debian Edu environment. For those without a
5213 central LDAP server with netgroups, one can instead touch the file
5214 <tt
>/etc/shutdown-at-night/shutdown-at-night
</tt
> to enable it.
5215 Perhaps you too can use it to save some power?

5227 on Squeeze. If you want to test a LDAP backed Kerberos server with

5234 <p
>I am very happy to report these changes and improvements since
5235 beta2 (there are more, see announcement for full list):
</p
>
5239 <li
>It is now possible to change the pre-configured IP subnet from
5240 10.0.0.0/
8 to something else by using the subnet-change tool after
5241 the installation.
</li
>
5243 <li
>Too full partitions are now automatically extended on the Main
5244 Server, based on the rules specified in /etc/fsautoresizetab.
</li
>
5246 <li
>The CUPS queues are now automatically flushed every night, and all
5247 disabled queues are restarted every hour. This should cut down on
5248 the amount of manual administration needed for printers.
</li
>
5250 <li
>The set of initial users have been changed. Now a personal user
5251 for the local system administrator is created during installation
5252 instead of the previously created localadmin and super-admin users,
5253 and this user is granted administrative privileges using group
5254 membership. This reduces the number of passwords one need to keep
5255 up to date on the system.
</li
>
5259 <p
>The new main server seem to work so well that I am testing it as my
5260 private DNS/LDAP/Kerberos/PXE/LTSP server at home. I will use it look
5261 for issues we could fix to polish Debian Edu even further before the
5262 final Squeeze release is published.

5264 <p
>Next weekend the project organise a

>With some computer hardware, one need non-free firmware blobs.
5278 This is the sad fact of todays computers. In the next version of
5279 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> based
5280 on Squeeze, we provide several scripts and modifications to make
5281 firmware blobs easier to handle. The common use case I run into is a
5282 laptop with a wireless network card requiring non-free firmware to
5283 work, but there are other use cases as well.
</p
>
5285 <p
>First and foremost, Debian Edu provide ISO images for DVD and CD
5286 with all firmware packages in the Debian sections main and non-free
5287 included, to ensure debian-installer find and can install all of them
5288 during installation. This take care firmware for network devices used
5289 by the installer when installing from from local media. But for
5290 example multimedia devices are not activated in the installer and are
5291 not taken care of by this.
</p
>
5293 <p
>For non-network devices, we provide the script
5294 <tt
>/usr/share/debian-edu-config/tools/auto-addfirmware
</tt
> which
5295 search through the
<tt
>dmesg
</tt
> output for drivers requesting extra
5296 firmware. The firmware file name is looked up in the Contents-ARCH.gz
5297 file available in the package repository, and the packages providing
5298 the requested firmware file(s) is installed. I have proposed to do
5299 something similar in debian-installer (BTS report
5300 <a href=
"http://bugs.debian.org/
655507">#
655507</a
>), to allow PXE
5301 installs of Debian to handle firmware installation better. Run the
5302 script as root from the command line to fetch and install the needed
5303 firmware packages.
</p
>
5305 <p
>Debian Edu provide PXE installation of Debian out of the box, and
5306 because some machines need firmware to get their network cards
5307 working, the installation initrd some times need extra firmware
5308 included to be able to install at all. To fill the PXE installation
5309 initrd with extra firmware, the
5310 <tt
>/usr/share/debian-edu-config/tools/pxe-addfirmware
</tt
> script is
5311 provided. Again, just run it as root on the command line to fill the
5312 PXE initrd with firmware packages.
</p
>
5314 <p
>Last, some LTSP clients might also need firmware to get their
5315 network cards working. For this,
5316 <tt
>/usr/share/debian-edu-config/tools/ltsp-addfirmware
</tt
> is
5317 provided to update the LTSP initrd with firmware blobs. It is used
5318 the same way as the other firmware related tools.
</p
>
5320 <p
>At the moment, we do not run any of these during installation. We
5321 do not know if this is acceptable for the local administrator to use
5322 non-free software, and it is their choice.

5324 <p

>The next version of
<a href=
"http://www.skolelinux.org/
">Debian Edu
5381 / Skolelinux
</a
> will include a new tool
5382 <tt
>sitesummary2ldapdhcp
</tt
>, which can be used to quickly set up all
5383 the computers in a school without much manual labour. Here is a short
5384 summary on how to use it to set up a new school.
</p
>
5386 <p
>First, install a combined Main Server and Thin Client Server as the
5387 central server in the network. Next, PXE boot all the client machines
5388 as thin clients and wait
5 minutes after the last client booted to
5389 allow the clients to report their existence to the central server. When
5390 this is done, log on to the central server and run
5391 <tt
>sitesummary2ldapdhcp -a
</tt
> in the
<tt
>konsole
</tt
> to use the
5392 collected information to generate system objects in LDAP. The output
5393 will look similar to this:
</p
>
5395 <p
><blockquote
><pre
>

5403 enter password: *******
5405 </pre
></blockquote
></p
>
5407 <p
>After providing the LDAP administrative password (the same as the
5408 root password set during installation), the LDAP database will be
5409 populated with system objects for each PXE booted machine with
5410 automatically generated names. The final step to set up the school is
5411 then to log into
<a href=
"https://oss.gonicus.de/labs/gosa/
">GOsa
</a
>,
5412 the web based user, group and system administration system to change
5413 system names, add systems to the correct host groups and finally
5414 enable DHCP and DNS for the systems. All clients that should be used
5415 as diskless workstations should be added to the workstation-hosts
5416 group. After this is done, all computers can be booted again via PXE
5417 and get their assigned names and group based configuration
5418 automatically.
</p
>
5420 <p
>We plan to release beta3 with the updated version of this feature
5421 enabled this weekend. You might want to give it a try.
</p
>
5423 <p
>Update
2012-
01-
28: When calling sitesummary2ldapdhcp to add new
5424 hosts, one need to add the option -a. I forgot to mention this in my
5425 original text, and have added it to the text now.

>I serien med intervjuer av folk i
5435 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
>-miljøet, har jeg nå
5436 lyktes med å få tak i en skolemann som ikke er aktiv med utviklingen,
5437 men likevel har vært med nesten siden starten av prosjektet. Jeg
5438 ønsker derfor velkommen til Paul Reidar Løsnesløkken, en mann med
5439 mange års erfaring i bruk av Skolelinux.
</p
>
5441 <p
><strong
>Hvem er du, og hva driver du med til daglig?
</strong
></p
>
5443 <p
>Jeg driftet tidligere IKT løsningen for skolene i
5444 <a href=
"http://www.nord-odal.kommune.no/
">Nord-Odal
</a
>. I dag er jeg
5445 IKT-konsulent for hele kommunen og samarbeider med
5446 <a href=
"http://www.hedmarken-ikt.no/
">Hedmark-IKT
</a
> for best mulig
5447 tjenester til kommunen. Jeg har bakgrunn som elektronikkreparatør og
5448 grunnskolelærer og har tatt en del fag innen IKT, i hovedsak
5449 driftsfag. IKT i Nord-Odal kommune blir i dag driftet av Hedmark IKT
5450 som er et samarbeid mellom Løten, Stange, Grue, Hamar, Kongsvinger og
5451 Nord-Odal. Jeg er fortsatt
"IKT-personen
" på skolene i kommunen og
5452 følger opp og gjør enkelte mindre endringer der.
</p
>
5454 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5456 <p
>Kommunen satset på Skolelinux i
2004. Jeg var ikke med i
5457 beslutningsprosessen den gang, men ble likevel med fra starten når
5458 dette ble levert.
</p
>
5460 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5462 <p
>Fordelene med Skolelinux er rask oppstart, sentral drift av
5463 klientene, klienter som jobber raskt og effektivt, bedre
5464 funksjonalitet på eldre utstyr og en ganske god programpakke med fri
5465 programvare som følger med. Løsningen med halvtykke klienter gjør at
5466 prosessering skjer lokalt med alltid ferske maskiner.
</p
>
5468 <p
>Skolelinux kan fungere godt på gammelt utstyr, men det er klart at
5469 utstyr også blir for gammelt selv for Skolelinux. I forbindelese med
5470 at vi nylig fikk nye servere og ny installasjon kastet jeg ut ca
60
5471 klienter som fortsatt var i drift etter at de var kjøpt godt brukt i
5472 2004. Noe var rundt
15 år gammelt, men var fortsatt i bruk. Noen
5473 klaget på at det nå gikk veldig tregt på en del pedagogiske nettsider
5474 med flash o.l. Det er fullt forståelig.
</p
>
5476 <p
>Jeg fikk nylig et spørsmål fra ungdomsskolens rektor om jeg kunne
5477 legge inn
<a href=
"http://freemind.sourceforge.net/
">FreeMind
</a
>, et
5478 tankekartprogram , på skolens elev-Windowsmaskiner. Lærerne hadde
5479 vært på kurs og ville ta dette i bruk. Skolen har ca halvparten av
5480 elevmaskinene på bærbare Windowsmaskiner. Da kunne jeg fortelle at
5481 dette programmet allerede lå inne på den nye Skolelinuxløsningen
5482 som nettopp var satt i drift, klart til bruk.
</p
>
5484 <p
>Vi har de bærbare maskinene på ungdomsskolen i domene med
5485 Skolelinux. Dette fungerer også meget bra nå. Elevene får opp en
5486 midlertidig windowsprofil når de logger på. Denne profilen slettes
5487 etter at de logger av, noe som medfører rene profiler hver gang de
5488 starter opp en maskin. De må lagre i sin Skolelinprofil, noe som
5489 medfører at de får tak i sine filer uavhengig av om de starter en
5490 Windowsmaskin eller en Skolelinuxklient. Det er mye mindre trafikk i
5491 det trådløse nettet etter at ikke hele profiler blir lastet opp til de
5492 enkelte Windowsmaskinene og tilbake når man avslutter. Jeg vet ikke om
5493 dette er standardoppsett i Skolelinux, men slik er vårt oppsett
5496 <p
>Vi har i flere år satt opp vår løsning slik at skriverkøer slettes
5497 og skrivere startes hver natt. Hyggelig å høre at dette nå skal bli
5498 en standard i Skolelinuxløsningen. Dette har vært en god hjelp for
5501 <p
>Elevene er lite opptatt av om de jobber på en Skolelinux eller en
5502 Windowsmaskin bare de har de programmene de trenger og at det virker
5503 når det skal brukes. Vi kjører mest mulig de samme programmene på
5504 Windows som i Skolelinux, som f.eks Audacity og LibreOffice.
</p
>
5506 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5508 <p
>Lærere bruker hos oss Windows. Dette fordi de da selv har mer
5509 kontroll over sin maskin, kan bruke den overalt, og kan legge inn
5510 programmer selv når de trenger noe i forhold til kurs o.l de er
5511 på. Jeg tror lærernes selvstendighet her gjør dem tryggere på IKT-bruk
5512 generelt. Det at de av og til får opp advarsler og lignende gjør også
5513 at de må tenke igjennom og spørre om ting rundt datasikkerhet.
</p
>
5515 <p
>Det er en del programmer vi bruker som ikke finnes for Linux. Mest
5516 brukt er nok Photostory3 som brukes i mange sammenhenger, særlig på
5517 ungdomsskolen, bl.a. til å lage herbarier (plantesamling) . Dette
5518 finnes gratis for Windows, men er ikke fri programvare. Vi er opptatt
5519 av at programmer elevene bruker på skolen også kan brukes gratis
5520 hjemme. Det er også en del programmer som brukes til spesielle elever
5521 som bare går i Windows. Det er viktig med fokus på funksjoner og ikke
5522 på hvilket OS man bruker.
</p
>
5524 <p
>For oss er det kombinasjonen mellom Skolelinux og Windows som gir
5525 oss en god og hel løsning. Skolelinux er best der de er gode.
</p
>
5527 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5529 <p
>Selv er det LibreOffice jeg bruker til daglig. Jeg bruker selv en
5530 Windowsmaskin. Jeg har benyttet en del fri programvare i forbindelse
5531 med sjekking av trafikk i nettverk, slik som Wireshark, men dette er
5532 jo ikke aktuelt for skolene. Jeg er generelt glad i programmer som
5533 fungerer på både Linux og Windows og gjerne MAC.
</p
>
5535 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5536 skoler til å ta i bruk fri programvare?
</strong
></p
>
5538 <p
>Det er viktig at det benyttes programmer som elevene også kan ta i
5539 bruk hjemme. Det skal da være enkelt, lovlig og gratis for
5540 elevene. Da er jeg ikke lenger veldig opptatt av om det kalles
"fri
5541 programvare
". For skolene tror jeg
"gratis
" og
"funksjonelt
" er bedre
5542 begreper enn
"fri
" i forhold til programmer. De fleste skiller nok
5543 ikke mellom
"fri
" og
"gratis
". Det er nå svært mange elever som
5544 benytter OpenOffice eller LibreOffice som sin primære kontorpakke

>During christmas, I have been working getting the next version of
5601 <a href=
"http://www.skolelinux.org/
">Debian Edu / Skolelinux
</a
> ready
5602 for release. The initial problem I looked at was particularly
5603 interesting.
</p
>
5605 <P
>The installer would hang at the end when it was doing it
5606 post-installation configuration, and whatevery I did to try to find
5607 the cause and fix it always worked while I tested it, but never when I
5608 integrated it into the installer and ran the installation from
5609 scratch. I would try to restart processes, close file descriptors,
5610 remove or create files, and the installer would always unblock and
5611 wrap up its tasks.
</p
>
5613 <p
>Eventually the cause was found. The kernel was simply running out
5614 of entropy, causing the Kerberos setup to hang waiting for more.
5615 Pressing keys was adding entropy to the kernel, and thus all my tries
5616 to fix the problem worked not because what I was typing to fix it, but
5617 because I was typing.
</P
>
5619 <p
>The fix I implemented was to add a background process looking at
5620 the level of entropy in the kernel (by checking
5621 /proc/sys/kernel/random/entropy_avail), and if it was too small, the
5622 installer will flush the kernel file buffers and do
'find /
' to
5623 generate some disk IO. Disk IO generate entropy in the kernel, and is
5624 one of the few things that can be initated from within the system to
5625 generate entropy.

5644 Denne gangen har jeg besøk av et avtroppende styremedlem i

5650 <p
>Jeg heter Peter Hansteen, og jobber til daglig som seniorkonsulent
5651 i EDB ErgoGroup i Bergen. I praksis betyr det systemadministrasjon på
5652 Unix (primært Solaris, men en viss komponent av Linux). Men Solaris
5653 er for meg et relativt nytt bekjentskap, hovedplattformen min har
5654 generelt vært OpenBSD og til dels FreeBSD.
</p

5656 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5658 <p
>Jeg husker ikke helt alle detaljene mer ;) - men jeg tror det var
5659 gjennom news-gruppen no.it.os.unix.linux.diverse, efn-listen og
5660 etterhvert også BLUG-miljøet her i Bergen. Vi hadde et par
5661 Skolelinux-sentrerte BLUG-møter for noen år siden, og det har vært et
5662 par Skolelinux-utviklersamlinger her.

>Hva er fordelene med Skolelinux slik du ser det?
</strong

5666 <p
>Jeg bruker dessverre ikke Skolelinux daglig. Men slik jeg kjenner
5667 prosjektet har det vært i stand til å ta opp i seg det beste av fri
5668 programvare i mange kategorier, så fra et sysadmin-perspektiv ser det
5669 ut som en svært behagelig sak. For brukerne er det vel både en fordel
5670 og en ulempe at det ikke er Windows. Men vi håper at fordelene med et
5671 fritt system etterhvert vil bli åpenbare for både elever, lærekrefter
5672 og foreldre.

5674 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

5676 <p
>Vel, ulempen er vel først og fremst at andre aktører med mer
5677 kapitalmuskel har klart å etablere seg som det både lærere og foreldre
5678 føler seg trygge på, selv om det etter mitt hode ikke er noen grunn
5679 til å være spesielt trygg på de kommersielle alternativene.

5681 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

5683 <p
>Når jeg får bestemme helt selv, bruker jeg kun fri programvare. Da
5684 helst med vekt på ting som kjører greit på OpenBSD. Hjemme er det
5685 OpenBSD, Ubuntu eller FreeBSD vi bruker. På skrivebordet er det en
5686 avveining mellom Gnome, KDE eller hva-det-nå-heter som er
5687 standardvalget i Ubuntu, ellers er det de kjente tingene som
5688 LibreOffice, Emacs, mplayer. På server er det selvfølgelig Apache,
5689 for overvåking både OpenNMS og Nagios (det bare ble sånn, og
5690 forskjellige siter). Jeg skriver til tider om slikt jeg holder på med
5692 <a href=

5694 <p
>Men vi må nevne at selv vi har en Microsoft-ting som vi slår på når
5695 vi av en eller annen grunn må. Det betyr igjen vanligvis når en
5696 mobiltelefon eller en annen lukket elektronisk dings krever kontakt
5697 via en slik for å få oppdateringene sine.

5705 <p

5706 sentral sak er å fokusere på fri programvare og åpne standarder som de
5707 demokratiske verdiene de faktisk er. Det har kanskje kommet litt for
5708 mye i bakgrunnen i forhold til strevet etter å lage det mest mulig
5709 'brukervennlige
' systemet. Det er en tung vei å gå, så det er
5710 forståelig at freenix-aktivister heller velger å skrive kode og annet
5711 som er mer lystbetont. Mer praktisk tror jeg vi må gjøre i alle fall
5712 to ting: For det første sørge for å fortsette med å levere det best
5713 mulige frie produktet, slik at det er lett å både komme i gang og
5714 holde systemene i daglig drift, og for det andre
2) spore opp mulige
5715 aktivister der de finnes, via lokale brukergrupper, sosiale medier
5716 eller annet og sørge for at de fortsetter å være aktive. Mer og
5717 mindre uformelle treff kan være nyttig i tillegg til de mer
5718 organiserte møtene med foredrag, konferanser og utviklersamlinger.

</strong
></p
>
5735 <p
>Mitt navn er Frode Jemtland, og jeg jobber i Hedmark IKT, som er et
5736 driftsselskap for Grue, Hamar, Kongsvinger, Løten, Nord-Odal og Stange
5737 kommuner. Her er jeg leder for avdelingen Løsninger og Arkitektur. Vi
5738 har i hovedansvar for servere, infrastruktur og løsninger som
5741 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
5743 <p
>Jobbet i IBM fra
2000, og da spesielt med Linux. Dette var da et av
5744 de mest tydelige linux prosjektene i Norge, og her ønsket jeg å
5745 bidra. Var aktivt med i prosjektet i
4-
5 år.
</p
>
5747 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5749 <p
>Fordelene slik jeg ser det er den sentraliserte driftmodellen, og
5750 alle de vel gjennomtenkte løsningene som er inkludert i denne
5751 løsningen. Samtidig er det basert på en stabil, og godt kjent
5752 plattform. Dette vil si at man har en løsning som skal være mye
5753 tilgjengelig, og hvor det er relativt enkelt å få tak i personer som
5754 kan mye om den grunnleggende plattformen.
</p
>
5756 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
5758 <p
>De største utfordringene med en løsningen er at den er intensiv på f.eks
5759 nettverk. I seg selv ikke et problem for en enkelt skole, men skal løsningen
5760 kjøres i større skala, med sentraliserte servere, så gir dette noen
5761 utfordringer.
</p
>
5763 <p
>Utifra hva jeg har sett på større installasjoner så er det ikke så
5764 enkelt å skjønne, hva som bør gjøres for at den skal skaleres opp, og
5765 da ta godt vare på alle sider av dette, ikke bare mer server å fordele
5766 last/trykk, men hvordan også beholde robustheten og fleksibiliteten i
5767 løsningen.
</p
>
5769 <p
>En annen utfordring er at stadig flere produkter som skal brukes i
5770 skoleløsningen ikke er laget til å kunne brukes i en
5771 skolelinuxløsning. Det blir derfor fort mye skreddersøm i de
5772 forskjellige installasjonene, for å få diverse pedagogiske programmer,
5773 webløsninger, smartboards, m.m. til å fungere. Man er også en for
5774 liten kundebase til at leverandørene ønsker å gjøre noe med
5775 utfordringen. Problemet overlates til oss.
</p
>
5777 <p
>Det er også en kontinuerlig utfordring rundt problemet med å holde
5778 programvare på stabile versjoner, kontra å få ny funksjonalitet. Dette
5779 er jo en konflikt mellom oss som ønsker å drifte en stabil, og
5780 kostnadseffektiv løsning, mot sluttbrukerne som ønsker seg funksjoner
5781 det er vant med fra andre løsninger, eller som de må ha for at et
5782 eller annet nytt produkt skal fungere i løsningen. Dette er en
5783 utfordring også for andre plattformer.
</p
>
5785 <p
>En siste utfordring som ikke har noe med løsningen å gjøre, men med
5786 det omkringliggende miljøet denne skal kjøre i, er at de enhetene som
5787 skal drifte dataløsninger for kommuner og fylkeskommuner begynner å
5788 profesjonaliseres, og er da avhengig av å ha standard løsninger for å
5789 drifte store brukermasser. MS er selvsagt klar over dette, og har jo
5790 nå flere områder de begynner å bli veldig dominerende på. Den største,
5791 og mest problematiske er katalogtjenesten. Man får snart ikke tak i
5792 større løsninger som ikke krever en AD. Når man da har store enheter
5793 som drifter både kommunalt ansatte og skoler, så vil det være et
5794 stordriftargument å standardisere på en katalog tjeneste, og da har
5795 man ikke noe valg. Her er alle slike driftsenheter for små til å få
5796 gjort om på dette. Her burde konkurransemyndighetene kommet på
5797 banen. Men konkurransetilsynet i USA griper sjeldent (og ikke før det
5798 har gått veldig lang tid) inn i monopolsituasjoner så lenge
5799 monopolisten er et amerikansk firma, så da har vel ikke andre
5800 myndigheter så mye de skulle ha sagt....
</p
>
5802 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
5804 <p
>Privat kjører jeg Debian på alle mine datamaskiner. Det gjør jeg
5805 også på min jobbmaskin. Vi har også
15-
20 linux servere av typene
5806 SuSE, Debian, Redhat, CentOS m.m. Jeg bruker derfor mye fri
5807 programvare. Av enkelt programmer kan sikkert masse nevnes. Hvis vi
5808 skal begrense oss til daglig, så må jeg si: OpenOffice, Firefox,
5809 Kontact, Kopete, Amarok,
5810 <a href=
"http://gramps-project.org/
">Gramps
</a
>, Kate, ssh, bash,
5811 rsync, backuppc m.m.
</p
>
5813 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
5814 skoler til å ta i bruk fri programvare?
</strong
></p
>
5816 <p
>Det er et godt spørsmål, som jeg har lurt på selv.
</p
>
5818 <p
>Argumentene som ofte har vært brukt om at ting koster mindre holder
5819 ikke mål når man ser på hva som faktisk koster penger. Det er de
5820 ansatte som er en kostnadsdriver. Det vil si at hvis man har et system
5821 som den ansatte kan, så vil en kostnad på dette systemet kunne
5822 forsvares ganske mye ved at den ansatte gjør dette raskere og
5823 effektivt. Også uten å måtte eventuelt leie inn folk.
</p
>
5825 <p
>Jeg syns det er viktigere å fokusere på prinsippet med å velge fri
5826 programvare, men det er også et felt hvor man fort møter lite
5827 forståelse blant de ansatte i skolen.
</p
>
5829 <p
>Her må nok strategien fortsette å være at de sentrale myndighetene
5830 må sende tydelige signaler for hva de ønsker at offentlige enheter
5831 skal gjøre. Det var mye positivt på gang ang. dette for et par år
5832 siden. Både med eNorge og eKommune planene, men dette syns jeg har
5833 stoppet opp. En del av dette kan jo kanskje være usikkerheten som
5834 etter hvert har blitt, når man har sett kompleksiteten i de
5835 prosjektene som har blitt igangsatt. Det har også blitt noe usikkerhet
5836 i markedet ref. Sun, Oracle, Novell, Microsoft m.m. Samtidig har jo
5837 også de proprietære programleverandørene sørget for å endre sine
5838 lisenser slik at man uansett ikke slipper unna kostnaden til deres
5839 produkter, selv om man skulle velge alternativer. Da er det økonomiske
5840 argumentet, som jeg nevnte tidligere, spilt ganske godt ut over
5841 sidelinjen.

5865 hadde vel hørt om prosjektet i media før en gjeng i Trondheim startet
5866 opp SPIST, Skolelinux-prosjektet i Sør-Trøndelag, hvor vi hjalp noen
5867 skoler i nærområdet med å installere Skolelinux og finne brukt
5868 IT-utstyr til disse. Det var moro å gjøre noe praktisk for å spre
5869 Skolelinux, og å se hvor fort gjort det var å sette opp utrangerte
5870 klientmaskiner og få disse opp som tynnklienter på helt nye datasaler
5871 på skolene, kun med kostnaden til servere.

5873 <p

5875 <p
>Det er et system spesielt skreddersydd for drift av et stort antall

5877 er enkelt og billig å installere og drifte, og det trenger ikke ny
5878 maskinvare for god ytelse.

5884 litt gammel programvare pga. at den følger Debian sine utgivelser.
5885 Kanskje man skulle vurdert en versjon basert på Ubuntu eller andre
5886 distribusjoner i tillegg?

5894 OI Shopping list, Shuffle, ZXing, OI Notepad og ADW Desktop. På jobb

>En bør fokusere på totalkostnader inkludert driftsbehov,
5902 fleksibilitet, åpenhet og ikke låsing til en leverandør framfor sparte
5903 lisenskostnader, samt programvarens kvalitet og fortrinn, og at den
5904 fritt kan brukes på et ubegrenset antall PC-er, også hjemme hos
5905 elevene. En bør også forbedre den fri programvaren ved testing,
5906 bugrapportering og kodebidrag om man kan, og ikke anbefale programvare
5907 uten at man har forsikret seg at den har tilstrekkelig kvalitet,
5908 ellers kan man lett oppnå det motsatte. Tror en bør selge inn
5909 konseptet til fylkes-/statsnivå, kanskje med bidrag til
5910 utviklingsarbeid fra disse som alle landets skoler kan få glede

>Mine bloggposter om Linux i skolene i Norge førte til at inspektør
5921 og ildsjel på Harestad skole tok kontakt og fortalte at de bruker
5922 Linux på sin skole, og lurte på om de kunne bidra til å gjøre
5923 fordelene kjent. Riktig nok bruker de ikke
5924 <a href=
"http://www.skolelinux.org/
">Skolelinux
</a
> på denne skolen,
5925 men jeg synes dette er en god anledning til å gjøre flere fasetter
5926 rundt Linux-økosystemet kjent, og tok et lite intervju.

5928 <p

5930 <p
>Mitt navn er Odin Hetland Nøsen og er en
70-modell. Jeg er bosatt i
5931 Stavanger og jobber nå på
9. året som undervisninginspektør på
5932 Harestad skole i Randaberg kommune (nabokommune til Stavanger).

></p
>
5936 <p
>I
2002 begynte daværende IKT-ansvarlige og jeg et arbeid på skolen
5937 med å gå over fra Win98 til... noe annet. Vi testet en rekke
5938 forskjellige løsninger, deriblant Skolelinux, men endte opp med
5939 RedHat. Skolelinux var den gang ikke modent for det vi ville ha. Jeg
5940 har siden fulgt jevnlig med på hva skolelinux holder på med, men har
5941 hele tiden vært bedre fornøyd med vår egen
"standardiserte
" løsning på
5942 RedHat/CentOS og Fedora. Vi snuser for tiden på Ubuntu som løsning på
5943 klientsiden.
</p
>
5945 <p
>I dag har vi på skolen vår en større linux-løsning med
400 klienter
5946 som kjører en blanding av LTSP (tynnklient) og DRBL (tykk klient uten
5947 harddisk) med en masse tjenere på serverrommet. Vi drifter hele
5948 sulamitten selv med webtjener, eposttjener, webmail, filtjenere,
5949 virtuelle tjenere osv. Og IT-ansvarlig har en
80% stilling som
5950 IT-ansvarlig - og så er han KoH-lærer i de resterende
20% :-)

>Du kan få en ide om hva vi holder på med om du går inn på
5953 <a href=

</a
>.
</p
>
5955 <p
>For å ta brodden av frykten for at ildsjeler gjør skolen sårbar om
5956 ildsjelene falle fra, har jeg forsikret kommunen og skolesjefen i
5957 Randaberg om at det finnes godt kommersielle tjenester vi kan benytte
5958 oss av - om det skulle bli nødvendig. Vi er tre stykker i kommunen som
5959 nå har
<strong
>god
</strong
> linux-kompetanse ift. å drifte et større
5960 system. IT-avdelingen i kommunen vil ikke ta på oss med ildtang -
5961 selv om vi nok har større IT-kompetanse mot linux enn det de selv har
5962 mot windows (de kjøper en
<strong
>masse
</strong
> konsulenttjenester
5963 fra ErgoGroup).
</p
>
5965 <p
>I kvantitet er Harestad og Grødem skole tilsammen et større
5966 IT-system enn resten av Randaberg kommune + Kvitsøy og Rennesøy, som
5967 kommunen også har driftsansvar for. Vi har som sagt rundt
800
5968 maskiner, mens kommunen med sitt driftsansvar har ansvar for rundt
500
5969 maskiner. Det er selvfølgelig litt forskjell i hvor kritiske
5970 tjenestene våre er, men det gir allikevel et litt rart bilde når
5971 IT-avdelingen overhode ikke er interessert i å snakke med oss om
5972 hvordan vi gjør ting :-)
</p
>
5974 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
5976 <p
>Fra linux-perspektivet (ikke bare Skolelinux) er det en fordel av
5977 systemet er basert på fri programvare - og dermed fritt i ordets mange
5978 betydninger. Det er alt vi trenger: stabilt, relativt enkelt å drifte
5979 (tross alt - et større windowssystem er ikke enkelt å holde live det
5980 heller), rimelig i innkjøp og drift, og sist, men ikke minst, det er
5981 moderne for sluttbruker! Linux, i sine mange varianter,
5982 <strong
>ser
</strong
> nytt ut, fordi det hele tiden blir
5983 oppdatert. Derfor lever systemet opp til hvordan elever forventer at
5984 et moderne GUI skal være (i motsetning til WinXP :-).
</p
>
5986 <p
>Vi var veldig pragmatiske da vi begynte med linux i skolen. Det var
5987 billig, det fungerte og kunne bruke alle de gamle windows-maskinene
5988 som
"nye
" tynne klienter. I dag er vi mer bevisste fri
5989 programvare-tilhengere. Vi har oppdaget hva det er - og vi liker
5992 <p
>En av de
<strong
>store
</strong
> fordelene med fri programvare er at
5993 vi kan installere tjenester vi ønsker å tilby brukerne våre - uten å
5994 måtte tenke på om vi har råd til lisensene (fordi det er ingen). Alt
5995 vi setter i produksjon er ut i fra brukernes behov og vår kapasitet
5996 til å drifte dem. Vi skreddersyr tjenestene etter behovet og dermed
5997 trenger vi ikke ende opp med å kjøpe en pakke der vi egentlig bare var
5998 interessert i en liten del av den.
</p
>
6000 <p
>Bruk av linux frigjør ikke økonomiske midler, fordi midlene til IKT
6001 i skole er for få i utgangspunktet - men vi får så
6002 <strong
>mye
</strong
> mer igjen for dem når vi bruker en linux-løsning
6003 fremfor en windows-løsning. I praksis ser vi at vi måtte ut med det
6004 dobbelte på budsjettet vårt om vi skulle hatt en tilsvarende
6005 windows-løsning, som det vi i dag drifter med linux.

6007 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong

>
6009 <p
>Ikke all pedagogisk programvare er tilgjengelig. Det er en del
6010 programvare i skolen som er laget med utviklerverktøy som bare virker
6011 i windows, f.eks. Drillpro, LingDys/LingWrite. Det er også
6012 "programmer
" som bare virker om du har tilgang til Microsoft Office,
6013 f.eks. AskiRaski.
</p
>
6015 <p
>Vi sliter også litt med at video-codecer ikke alltid er like lett å
6016 få opp å gå på klientene. Det er alltid en eller annen videosnutt fra
6017 nrk.no som ikke er så samarbeidsvillig, uansett mediaplayer.

6019 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong

>
6021 <p
>Alt :-) På skolen bruker vi det som finnes og som er nyttig. Det vi
6022 bruker mest er Firefox (jobber med Chrome, fordi det er
6023 <strong
>mye
</strong
> raskere med Flash enn Firefox), OpenOffice (skal
6024 over til LibreOffice), GIMP osv. Standardpakken av
6025 sluttbrukerprogrammer.
</p
>
6027 <p
>På tjenernivå bruker vi OpenWebMail (skal over til Zimbra), Exim
6030 <p
>Personlig bruker jeg de fleste programmer over flere plattformer,
6031 men jeg har lagt meg til en vane å prioritere bruken av fri
6032 programvare også i Windows
7 og OSX.

6034 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6035 skoler til å ta i bruk fri programvare?
</strong

>
6037 <p
>Jeg er langt i fra sikker. For det første handler det mye om at
6038 IKT-avdelingen i kommunen ofte er de som styrer hva som er IKT på
6039 skolene - og de liker å bruke avtalene med Microsoft, som de garantert
6040 har fra før. Dessuten - Select
6-avtalen til skolene gjør Microsoft
6041 skvettbillig.
</p
>
6043 <p
>Vi la vekt på effektiv drift av systemet - og at vi kunne øke
6044 antall maskiner uten å måtte øke budsjett for utstyr eller personell
6045 særlig mye, enn om vi hadde gått for en Microsoft-løsning. I praksis
6046 ser vi at en ren linux-installasjon driftes til halve prisen av en
6047 Microsoft-løsning.
</p
>
6049 <p
>Vi har i praksis også sett at det lærerne (og elevene) liker er at
6050 vi tilbyr
<strong

</strong

6051 vanlige i en Microsoft-løsning. Det er ikke så vanlig at
6052 <strong

</strong

6053 også brukt som et vellykket argument mot Microsoft.
</p
>
6055 <p

6056 det. Problemet er å få dem som har makt til å bestemme det til faktisk

6073 <p
>Jeg heter Astri Sletteng. Jeg er lærer og IKT veileder ved Håkvik
6074 skole i Narvik kommune. Min bakgrunn når det gjelder IKT: Av formell
6075 utdannelse har jeg lærerutdanning, Master i skoleledelse og IKT for
6076 lærere. Har jobba som IKT veileder siden
2002.
</p
>
6078 <p
>Det viktigste for meg som IKT veileder er å få fundamentert den
6079 5. basisferdigheten, digital kompetanse ved skolen min på en god måte
6080 slik at hele skolesamfunnet tar i bruk IKT i alle fag. Dette arbeidet
6081 gjøres i nært samarbeid med skolens ledelse.
</p
>
6083 <p
>Min viktigste jobb som IKT veileder er å være motivator og pådriver
6084 i IKT arbeidet ved skolen.
</p

6086 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

6088 <p
>Jobber i en kommune hvor vi satser på Fri programvare. I
2004 ble
6089 det gjort et politisk vedtak om at vi skulle innføre Skolelinux ved
6090 alle skolene i kommunen. Jeg har dermed en god del erfaring med
6091 Skolelinux, samt annen fri programvare som Open Office, Joomla, Moodle
6094 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p

6096 <p
>Siden vi jobber med åpen kildekode kan vi få programmene og
6097 produktene tilpasset vår bruk. Det er jo heller ikke en ulempe at
6098 skolen kommer bedre ut økonomisk, men først og fremst er det viktig
6099 for oss at vi har digitale systemer som gjør at vi kan følge
6100 læreplanen i alle fag. Det syns jeg at vi kan gjøre gjennom
6101 Skolelinux.
</p
>
6103 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6105 <p
>Skolen er avhengige av å ha folk på IT avdelinga i kommunen som kan
6106 drive support, og være tilgjengelige når vi trenger hjelp. Det er en
6107 ulempe at ikke alle på denne avdelingen nødvendigvis er god på
6110 <p
>Vi har også noen utfordringer når det kommer til spesielle
6111 programmer som enkelte elever er avhengige av ? og som ikke er
6112 plattform uavhengige. Her har vi i Friprog-verden, men også
6113 departement en jobb å gjøre.
</p
>
6115 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6117 <p
>Skolen vår bruker Skolelinux, Open Office, Iceweazel (Mozilla),
6118 VLC, Tux paint, Scribus, FreeMind, GIMP, digiKam, Ksnapshot, GeoGebra,
6119 Moodle (innført på alle klassetrinn + som et administrativt verktøy)
6120 og Joomla som hjemmeside.
<p
>
6122 <p
>Det er de jeg kommer på i farten. I tillegg har vi Smartboard
6123 installert på server, men det regnes vel ikke som fri programvare?

6125 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6126 skoler til å ta i bruk fri programvare?
</strong
></p
>
6128 <p
>Først og fremst trenger skolen oppetider på sine datasystemer. Syns
6129 også at det at vi kan få tilpasset plattform og systemer til vår bruk
6130 er en god strategi å bruke.

6141 flinke folk. Denne gangen har jeg fått et ferskt styremedlem som

6146 <p
>Rubén Romero y Cordero,
81-modell, deltidspappa (
50%) for en jente
6147 på
6 år. Jobber i Oslo som Global Sales Executive hos Varnish Software
6148 og til daglig har jeg kontakt med kunder fra hele verden. Min
6149 forkjærlighet for fri programvare har gjort at jeg har nå flere års
6150 erfaring med salg av slike løsninger (bl.a. fra Redpill Linpro og
6151 Freecode) og mye innsikt og kunnskap om det globale IT-markedet.
6152 Ellers er jeg involvert i flere prosjekter bl.a. er jeg Ubuntu
6153 Community medlem, kontaktpersonen for Ubuntu Norge og driveren av
6154 SpreadUbuntu marketing prosjektet og nå fersk styremedlem i FRISK. Jeg
6155 har brukt GNU/Linux siden
1997.
</p

6157 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p
>
6159 <p
>Som Debian bruker siden slutten av
90-tallet var det uunngåelig å
6160 ikke komme bort i Skolelinux. Dette var vel i slutten av
2001 når jeg
6161 var student ved UiO. Flere år senere fikk jeg lastet og testet Venus
6162 (Skolelinux
1.0) på release dagen.
</p
>
6164 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6166 <p
>Fri programvare bygges sten for sten i det åpne, slik at koden og
6167 prosessen den lages på kan gjennomskues av andre enn de som har laget
6168 det. Det er et vitenskapelig og gjennomsiktig måte å lage programvare
6171 <p
>Skoler i vårt samfunn skal være steder hvor vitenskapelig kunnskap
6172 deles til alle. I dag har vi ikke et vitenskapelig tilnærming til
6173 hvordan programvaren som brukes på skolen lages. Skolelinux bringer
6174 inn at slik tilnærming i skoleverkets klasserom, siden
6175 operativsystemet er en åpent platform som gir skolene muligheten til å
6176 dra nytte av programvare som er laget av tusenvis av mennesker verden
6177 rundt og som gir elevene så vel som lærerne muligheten til å bruke,
6178 dele, forandre og forbedre OSet sitt uten begrensninger. I den
6179 forbindelsen representerer Skolelinux også konkrete resultater utfra
6180 samhandling på tvers av grenser.
</p
>
6182 <p
>Når det gjelder de tekniske fordelene av Skolelinux er jeg sikker
6183 på at andre enn meg har allerede beskrevet disse bedre enn det jeg
6184 kan. Men jeg kan likevel tilføye noe: Skolelinux som sådan er en
6185 community-drevet operativsystemplatform. Som i ethvert
6186 community-prosjekt har alle Skolelinux brukere muligheten til å
6187 påvirke retning av prosjektet og resultatet som gjenspeiles i
6188 programvaren. Dette kommer sjeldent frem og jeg mener at det er noe
6189 som burde fokuseres mer på.
</p
>
6191 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6193 <p
>De største ulempene er:
</p
>
6196 <li
>Mangel på kompetanse
</li
>
6197 <li
>Mangel av administrative verktøy som kunne hjelpe lokale IT
6198 avdelinger å bruke Skolelinux til mer enn bare en tjener for
6199 terminalklienter. Et eksempel: Zentyal sin web-dashboard.
</li
>
6202 <p
>Bedre og mer intuitive administrative verktøy kunne løst deler av
6203 problemet, men det er unektelig at ved bruk av Skolelinux må
6204 IT-personalet vite hva de gjør for å få ting gjort riktig, eller i det
6205 hele tatt. Med andre platformer er kompetansen enklere tilgjengelig og
6206 løsningene kan fungere på en tilfredstillende, om ikke riktig
6209 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6211 <p
>Har brukt GNU/Linux utelukkende sommitt skrivebord OS siden
2000. I
6212 dag bruker jeg Ubuntu og gjør det meste med friprogramvare verktøyene
6213 som er tilgjengelige der. Med over
20.000 programmer å velge mellom er
6214 dette mer enn nok for de fleste brukerne.

6216 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6217 skoler til å ta i bruk fri programvare?
</strong
></p
>
6219 <p
>Opplysning og pragmatikk. Vi prøver å løse problemer med bruk av
6220 programvare. De fleste utfordringene skolene har på IKT-siden kan
6221 løses ved hjelp av friprogramvareverktøy i dag. Det som trenges er
6222 opplysning, kunnskap og kompetanse.

6249 <p
>Skolelinux har jeg møtt ved flere anledninger opp gjennom åra, både gjennom
6250 entusiastiske skolelinuxbrukere og skeptiske
"forståsegpåere
" :-)
</p
>
6252 <p
>Jeg husker en leverandør av et stort OS for noen år siden mente at
6253 Skolelinux var kun for hackere og nerder og at ingen seriøse skoler
6254 kunne ta dette i bruk. Heldigvis er kunnskapen større nå og
6255 skikkelige
"IT-folk
" søker alltid å utvide sin kunnskap.
6257 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6259 <p
>Ja det er mange fordeler. Uavhengighet, stabilitet, åpenhet, standarder
6260 osv. Tror det er viktig at man ikke begrenser mulighetene på den plattformen
6261 elevene skal jobbe.
</p
>
6263 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6265 <p
>Det største hinderet er det vi opplever på andre områder rundt
6266 fri programvare, nemlig kunnskap. For mange er det trygt å velge det vi
6267 alltid har valgt. Fordi leverandørene rundt oss sitter på den kunnskapen og
6268 de vi støtter oss på har den samme. Hvis vi klarer å riste løs litt og
6269 glemme gamle kriger mellom operativsystemer og leverandører, men sette ned
6270 hva som er viktig og velge ut fra det, så hadde man kanskje kommet ut med
6271 litt andre resultat. Jeg tror IT-folk er konservative og velger tradisjonelt
6272 og det er synd.
</p
>
6274 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6276 <p
>Jeg bruker Ubuntu, Android, Jolicloud, Open Office, Zimbra, Picasa
6277 og Firefox samt en bråte med tjenester som er webbasert. Det eneste
6278 som er betalingslisens for er OSX. Ser at jeg jobber mer og mer i
6279 skyen og setter pris på alt jeg slipper egen klient til. Derfor er
6280 jeg veldig sjarmert av små kjappe operativsystemer som krever minimalt
6281 av maskinvaren.

>
6283 <p
><strong
>Hvilken strategi tror du er den rette å bruke for å få
6284 skoler til å ta i bruk fri programvare?
</strong
></p
>
6286 <p
>Tror en blanding av krav og informasjon er veien å gå. Krav om
6287 sikkerhet, oppetid og åpne standarder. Informasjon om muligheter og
6288 alternativer. Her har leverandører, IT-avdelinger og pedagoger en vei
6289 å gå sammen. Det er til slutt LÆRING det dreier seg om, og da må man
6290 få mest mulig læring for pengene man har.

>Sturle Sunde, ansvarleg for skulenettet i Flora kommune. Eg driv,
6308 vidareutviklar og er andrelinje brukarstøtte for datanettet ved
6309 skulane i Flora kommune.
10 skular og meir enn
700 maskiner med
6310 Linux, medrekna tynnklientar. Tidlegare jobba eg i mange år med
6311 unix-drift ved Universitetets senter for informasjonsteknologi ved
6312 Universitetet i Oslo.

6314 <p
><strong
>Hvordan kom du i kontakt med Skolelinux-prosjektet?
</strong
></p

6316 <p
>Det er vanskeleg å svare konkret på. Eg har drive med Unix og Linux i
6317 alle år, og Skulelinux er eit godt kjent prosjekt i miljøet. Det var
6318 først i
2008, då eg tok til i min noverande jobb, at eg fekk bruk for
6319 Skulelinux for alvor.
</p
>
6321 <p
>Jobben min skulle vere drift av eit nytt skulenett i Flora kommune,
6322 levert av eit firma eg ikkje vil reklamere for. Systemet skulle vere
6323 ferdig levert i september året før. Dette viste seg å ta mykje lenger
6324 tid, og i haustferien
2008 hadde dei endå ikkje klart å få opp ei
6325 fungerande løysing. Situasjonen var prekær for den største skulen i
6326 kommunen med meir enn
500 elevar på ungdomssteget. Skulen hadde brukt
6327 Skulelinux før, og var tilfredse med det. No hadde dei vore utan
6328 fungerande datasystem i nesten eit år. Difor fekk eg opp ein ny tenar
6329 utanfor prosjektet og installerte Skulelinux på den. Etter litt
6330 justering av konfigurasjonen med god hjelp av #skolelinux på IRC, var
6331 den nye tenaren oppe og gjekk med både tynne og halv-tjukke klientar.
6332 Autentisering gjekk mot det nye systemet, slik at elevar og lærarar
6333 framleis har same brukarnamn og passord over alt. Dette berre
6334 fungerte, og vi bestemte oss for å erstatte delar av løysinga vi
6335 skulle få levert med Skulelinux.
</p
>
6337 <p
>Det høyrer med til historia at det nye systemet eg skulle drive frå
6338 januar
2008 endå ikkje er ferdig levert. Dei jobbar med saka, seier
6339 dei, og har von om å fullføre leveransen i løpet av
2011.
</p
>
6341 <p
><strong
>Hva er fordelene med Skolelinux slik du ser det?
</strong
></p
>
6343 <p
>Det er veldig mange. Eg skal ta nokre få.
</p
>
6345 <p
>Den viktigaste fordelen er at det igrunn berre er ei maskin å passe
6346 på, og det er tenaren. Med andre løysingar har ein gjerne programvare
6347 og anna som skal vedlikehaldast på kvar enkelt maskin. Med Skulelinux
6348 kan alle feil rettast og alle program oppgraderast på alle maskiner
6349 samstundes ved å gjere endringa som må til på tenaren. Eg kan sitje
6350 på kontoret og passe på alle tenarane i kommunen derifrå.
</p
>
6354 <li
>Tynne klientar gjer det mogleg å bruke eldre utstyr lenge, so lenge
6355 tenaren er sterk nok. Ein liten tenar med eit par halv-moderne CPUar
6356 og
2 GiB RAM held lenge for eit typisk klasserom med
30 tynnklientar,
6357 og det er lett å utvide med fleire.
6359 <li
>Halvtjukke klientar gjer det mogleg å utnytte kapasiteten i litt
6360 nyare maskiner betre, og avlaste tenaren. Ingenting vert installert
6361 lokalt på desse heller, og harddisken kan gjerne koblast frå. Gode
6362 halvtjukke klientar kan kjøpast brukt for under
1000-lappen, og det er
6363 heile kostnaden. Ingen lisensar eller anna på toppen, og det er ikkje
6364 krav til kraftigare tenar heller.
6366 <li
>Det er Linux. Vi har ikkje noko kluss med drivarar, dei berre er
6367 der. Heller ikkje med virus, dei finst i realiteten ikkje. Eller med
6368 elevar som klussar med installert programvare, for dei klarar ikkje å
6369 øydeleggje for nokon andre enn seg sjølve.
6373 <p
>Skulelinux er lagt opp til å vere veldig lett å installere rett ut
6374 av boksen på ein heil skule av ein interessert lærar. Det er ofte ei
6375 god løysing for skulen. Å ha nokon til stades som kjenner systemet og
6376 kan forklare enkle ting eller løyse problem der og då, er uvurderleg
6377 viktig for ein stressa lærar fem minutt før det ringer inn.
</p
>
6379 <p
><strong
>Hva er ulempene med Skolelinux slik du ser det?
</strong
></p
>
6381 <p
>All den ferdige konfigurasjonen gjer det tungvint å tilpasse
6382 Skulelinux til eit system som skal fungere saman med mange andre
6383 installasjonar i eit felles datanett for skulane i ein kommune. Det
6384 heile er prekonfigurert for ein skule, og utviding til mange skular
6385 med eigne tenarar er ikkje berre enkelt.
</p

6387 <p
><strong
>Hvilken fri programvare bruker du til daglig?
</strong
></p
>
6389 <p
>Eg brukar mest alle små hjelpeprogram som føl med operativsystemet,
6390 samt scriptspråket perl. Elles er Firefox/Iceweasel, Gnome-terminal
6391 og ssh i kontinuerleg bruk. Av Linux-distribusjonar brukar eg både
6392 Debian, Ubuntu, SuSE og RedHat dagleg. Eg prøvar å finne det verktyet
6393 som passar best til kvar del av jobben.

6396 skoler til å ta i bruk fri programvare?
</strong

6398 <p
>Det er to målgrupper ein må sikte mot. Det eine er alle skulane som
6399 manglar eller har eit lite tilfredsstillande opplegg i dag, og ikkje
6400 har råd til å kjøpe noko nytt og blankpussa opplegg. Der er det om å
6401 gjere å gjere det enkelt for skulane å finne Skulelinux, og gjere det
6402 enkelt for dei å få hjelp til installasjon på skulen. Gjerne med
6403 lokale kontaktpersonar. Her er det dugnadsinnsats som må til, for
6404 desse skulane har ikkje råd til å betale for dette.
</p
>
6406 <p
>Den andre og kanskje viktigare målgruppa er dei meir eller mindre
6407 profesjonelle kundane. Alle store offentlege innkjøp, inkludert
6408 innkjøp av nytt datasystem for skular, må ut på offentleg anbod.
6409 Offentlege anbod er mykje meir lukka enn dei gjev inntrykk av, og både
6410 regelboka og boka med triks for å sminke tilbodet er tjukk. Det er
6411 vanskeleg å komme inn utan eit solid salsapparat i ryggen. Kanskje
6412 Skulelinux skulle prøve aktivt å få seg eit partnarskap med eit av dei
6413 store som gjerne vil sterkare inn på den offentlege IT-marknaden?
6414 Nokon som kjenner triksa og har krefter til å ta opp kampen mot både
6415 dårlege anbod og Rudolf Blostrupmoen IT AS. Leveranse til skulane i
6416 ein kommune er ein god måte å få ein fot inn døra som leverandør til
6417 ein lukrativ kommunemarknad som kjøper alle tenester. Ta kontakt med
6418 nokon som er passeleg store og ikkje er Microsoft-partnar, og fortell:
6419 «Vi har eit ferdig produkt som du kan selje. Nei vi skal ikkje ha for
6420 det. Du kan gjerne gjere kva du vil med det, berre vi får lov til å
6421 hjelpe deg. Målgruppa er alle kommunar, og det er noko dei vil ha.
6422 Det er eit godt produkt, brukt av mange og godt likt.»

>Jeg leste en artikkel om en dugnadsinstallasjon av Skolelinux på en
6449 skole på Jæren et sted. Tanken om dugnad og frihet appellerte til
6450 meg. Da vi skulle bygge ny skole var det en del vi måtte spare på,
6451 fordi vi beveget oss mot en kostnadssprekk. Kabling og investering i
6452 PC-er var en av tingene vi sparte på. Derfor kjøpe vi
72 pc-er for
390
6453 pr stk. En filtjener og en applikasjonsserver.

>Fordelen er at så mye er satt opp fra starten. I tillegg er det
6458 tydelig at pakka er laga for skoleverket. Brukerne har egne
6459 skrivebord, tilgang på mange gode verktøyprogrammer. Vi slipper å
6460 tenke på virus. Brukerne har ikke mulighet til å ødelegge
6461 klientoppsett, men har gode muligheter til å endre eget oppsett. Dette
6462 tror jeg er inspirerende og kjekt for mange brukere. Mappestrukturen
6463 er ferdig og det er
"enkelt
" å designe lokale mappestrukturer via
6464 skeleton. Noen av oss i skoleverket mener skolen skal være en
6465 "mot-kultur
". Da er Skolelinux et av valgene man kan ta. Et annet er å
6466 spise på indisk restaurant i stedet for Mc Donald
's når vi er på bytur
6467 osv.. Ordene deling, frihet, dugnad osv er positive ord i
6468 skoleverket. Det er viktig at elevene blir bevisst dette.

>Kompabiliteten er selvsagt et problem, selv om det er mindre nå enn
6473 før. For IKT-personer på skolene som skal drifte dette er det
6474 problematisk med kommandoer i terminalen. I tillegg er det alt for
6475 mange programmer i Skolelinux som ikke blir brukt. Jeg tror
6476 Skolelinux er tjent med å tone ned begrepet pedagogisk programvare.
6477 Slik jeg ser det finnes ikke denne kategorien programmer lengre slik
6478 de gjorde før, som frittsående programmer som installeres på en
6479 datamaskin eller på serveren. Det finnes en del spesialpedagogiske
6480 programmer, som Textpilot, LingDys, LingRight, AskiRaski, Ny i Norge
6481 osv. Men dette er programmer for enkelt-elever eller små grupper av
6482 elever. Det som bør være fokus er at alle undervisningsressurser som
6483 lages for nettet skal være nettleseruavhengig.

6487 <p
>OpenOffice bruker jeg til vanlig kontorarbeide. VLC bruker jeg som
6488 videoavspiller og av og til streaming av film. Gimp bruker jeg i
6489 undervisningen til bildemanipulering. Firefox og Chrome er mine
6490 favoritt-nettlesere. Firefox har lenge vært førstevalget mitt, nå
6491 bruker jeg mest Chrome. Opplever den som raskere og smidigere enn
6492 Firefox. Ubuntu bruker jeg som dualboot på jobb-maskinen min i
6493 tillegg til at alle PCer hjemme har en eller annen Ubuntu-distribusjon
6494 installert. Jeg bruker Clonezilla på Ubuntu
10.04 til kloning av
6495 datamaskiner på jobb. Det er selvsagt en haug andre frie programmer
6496 jeg bruker men jeg bruker dem ikke daglig. Jeg kan ramse opp:
6497 recordmydesktop, cinelerra, acidrip, soundjuicer, audacity, NX
6498 (no-machine), Kino, Rythmbox...

</strong
></p
>
6503 <p
>Jeg tror oppsøkende virksomhet er den rette strategien.
6504 Ressurspersoner gjør avtaler med rådmenn, skolesjefer, rektorer. Det
6505 er slik konkurrentene gjør det. Fokuset i slike samtaler bør være
6506 kost-nytte. Dersom personer med økonomisk ansvar ser at de kan få
6507 like godt tilbud til mindre utgifter, tror jeg det er mulighet til å
6508 få innpass. Dersom de også kan få konkrete tilbud på drift i slike
6509 samtaler, vil de kanskje bli litt mer interesserte i hvor mye penger
6510 som faktisk går til IKT i skolene. Det er også viktig at vi ikke
6511 firer for mye på krav til datamaskiner. Det er flott at Skolelinux
6512 går på
"utrangert
" utstyr, men dette bør bare presenteres som et
6513 alternativ. Skolelinux-installasjoner med utrangert utstyr er ikke å
6514 foretrekke dersom man kan unngå det. Det skaper ikke entusiasme hos
6515 brukerne (elever og lærere) når de bruker gamle datamaskiner som går
6516 tregt. Det er kjempefint med skoler som har kommet seg frem til
6517 Skolelinux og fri programvare av seg selv, men de lever på nåde.
6518 Slike valg må fundamenteres hos skoleeier.

2001 der var det skrevet om
6550 Skolelinux. Artikkelen ga meg lyst til å prøve ut systemet.
</p

6552 <p
>Det startet i
2002 ved at jeg installerte en av de første utgavene
6553 av Skolelinux på en standard pc på Solneset skole i Tromsø. Denne var
6554 oppe fram til desember
2003 da jeg sluttet på den skolen og begynte i
6555 ny jobb i Narvik kommune.

2004 kun
2 servere på da totalt
15
6558 skoler. Disse var Windows NT baserte. På disse to skolene var det lite
6559 med maskiner. Jobben med å få Narvik Kommune opp på akseptabelt nivå
6560 virket å være formidabel. Men med hjelp av gode kollegaer og leder
6561 skrev jeg en IKT plan for Narvik kommune som ble vedtatt av politikere
6562 i august
2004. I denne planen ble det bestemt at Narvik kommune skulle
6563 bruke Skolelinux. Her ble det også satt av midler til kabling av god
6564 infrastruktur på alle skoler samt innkjøp av nye datamaskiner. Så i
6565 dag har vi
17 servere hvorav
13 er på Skolelinux, med ca
1500 klienter

6649 men det virker ut som det ikke skjer noe mer på. I tillegg var vi med

6657 en arkitektur med sentral-drift som gir mange driftfordeler. I

>Kommunen min har to omtrent jevnstore tettsteder, og en
6702 ungdomsskole i hvert av tettstedene. Den minste av disse har ca
300
6703 elever og til denne sogner det
3 barneskoler. Den største har ca
350
6704 elever og til denne sogner det
4 barneskoler.
</p
>
6708 <li
>Kommunen har i veldig lang tid forsømt IKT i skolen, og det har
6709 bare blitt gitt smuler i ny og ne. Det er kun den største av
6710 ungdomsskolene som har hatt en skikkelig datapark, og dette takket
6711 være en naturfaglærer som ble lei av å vente på kommunen. Det gjorde
6712 at vi bestemte oss for å ta ting i egne hender, og da vha
6713 skolelinux. En testinstallasjon med
10 gamle PCer ble gjort, og vi så
6714 raskt at dette var veldig lovende. Neste etappe var å gi alle lærere
6715 egen PC på arbeidsplassene sine (
2004), og så sette opp
16 PCer på to
6716 datarom. Vi har kun basert oss på å kjøpe inn brukte maskiner, og
6717 aldri dyrere enn
1000 kr pr klient. For to år siden så hadde vi
6718 klienter i alle klasserom, og totalt hadde vi da rundt
250 stk. Rundt
6719 40 klienter brukes av lærerne og kjører på en egen server. Elvene har
6720 resten, og kjører også en egen server. Servere har vi også kjøpt
6721 brukt,
2 år gamle servere koster
6-
7000 kroner.
</li
>
6723 <li
>Skolen vår er et relativt gammelt bygg, men en meget dyktig
6724 vaktmester har sammen med IKT-ansvarlig/Naturfaglærer lagt kabler til alle
6725 rom. Gradvis har vi byttet ut billige svitsjer med mer solide saker
6726 som er mulig å fjernstyre.
</li
>
6728 <li
>Vi har i all hovedsak greid å få dette til over eget budsjett, men
6729 vi har også passet på å få penger når de andre skolene har fått
6730 bærbare PCer til lærere osv.

6733 en maskinpark som de andre av kommunens skoler bare kan drømme
6738 <p
>Så skjer det som ofte skjer. Det kommer en eller annen
6739 selger/blåruss og skal fikse ALT. I vårt tilfelle betyr dette også
6740 sentralisering av drift. Den ny-ansatte på kommunens IT-avdelingen
6741 skal også ha jobb, og ser for seg å ta over skoledriften. Kommunen
6742 kjøper inn eksterne driftstjenester, og nekter i samme slengen å ta
6743 hensyn til skolen vår. Dette til tross for at vi alene har like mange
6744 datamaskiner som de andre til sammen.
</p

6748 <li
>Det blir krevd at vi skal innlemmes i de kommunale systemet, og
6749 det er VI som får ansvar for at dette kommer på plass. Og det er her
6750 de horrible tingene begynner å skje.

6757 at vi må bruke en terminalløsning mot kommunal server. Ikke i seg selv
6758 et problem i følge IKT-ansvarlig hos oss. Men kommunens IT-avd nektet
6759 faktisk å åpne de porter OSV som vi måtte bruke.
</li
>
6761 <li
>Vi blir pålagt å flytte på innsiden av det kommunale
6762 nettverket. Dette gjorde at vi mistet hjemmekontor for lærere og
6763 elever. Å få åpnet porter i kommunal brannmur var ikke
6764 aktuelt. Mulighet for fjerndrift ble også vekk i samme slengen.

6766 <li
>Vår LMS Moodle er ikke mulig å nå for elevene og lærerne.
6770 <p
>Den andre ungdomsskolen i kommunen begynner så å kreve at de skal
6771 få bedre datatetthet, og komme opp på et nivå som ligner det vi
6772 har. De ser at vi kan avholde eksamen hvor alle
10. klassingene får
6773 sitte ved hver sin PC. Og de har fått tilbakemelding (klager) fra VGS
6774 om manglende datakompetanse på elevene som kommer fra dem. Dette fører
6775 videre til at kommunen endelig innser at de må ta grep.
</p

6777 <p
>Grepet betyr sentralisering, og farvel til vår plattform får vi
6778 høre. Det blir gjort en rekke bestemmelser og vedtak som vi ikke får
6779 være en del av. Det blir helt klart at vi må redusere antall maskiner,
6780 og det skal satses på bærbare maskiner. Siden vi ikke har fått tatt
6781 del i prosessene som angår oss, så bruker vi fagforening. Vi har ikke
6782 blitt hørt i forbindelse med endringer som er betydelig for vår
6783 hverdag, og greier å stoppe omlegging. I tillegg så har vi et politisk
6784 vedtak i kommunen på at vi skal kjøre Linux på elevnett, og dette
6785 vedtaket kan ikke administrasjonen i kommunene helt uten videre
6786 tilsidesette.

6871 <p
>Jeg glemte å nevne at vi nå nesten ikke bruker tid på å drifte
6872 systemet vårt, noe som gjør at det aller meste av tid blir brukt til å
6873 støtte lærerne og elevene. F.eks så bruker vår IKT-ansvarlig den
6874 første timen på jobb,
0730-
0830 kun til å gå ute på arbeidsplassene
6875 til læreren. Dette for å kunne svare på små og store problem, gi tips
6876 og råd, eller bare for å plukke opp hva som er behovet ute i
6877 undervisningsarealene. Det er dessverre ikke slik at alle lærerne har
6878 nok digital kompetanse til å kunne formulere alle spørsmålene de har,
6879 men ved å kunne få vise eller lufte tanker med IKT-ansvarlig så er det
6880 utrolig hva som kommer fram.
</p

6884 <li
>Jeg ser at mange bruker økonomi som argument i forhold til å bruke
6885 SkoleLinux, og jeg skal ikke legge skjul på at det var dette som i
6886 utgangspunktet var årsaken til vårt valg. Men diskusjonene og kampen
6887 med kommunens IT-avdeling har gjort at vi har fått et noe annet
6888 fokus. Fordelene med drift og stabilitet, gjør at vi ville ha valgt
6889 samme løsning selv om den var dyrere. At vi slipper langt billigere
6890 unna, som følge av
0,- lisenskostnader og lave maskinvarekostnader, er
6891 bare en bonus.
</li
>
6893 <li
>Etter å ha kranglet oss til å få skikkelig oversikt over hva de
6894 andre skolene i kommunen bruker på IT, så har vi fått gehør for å få
6895 samme midler til innkjøp. Dette har gjort at vi nå kan kjøpe inn
6896 utstyr som de andre skolene bare kan se langt etter. Vi har nettopp
6897 kjøpt inn
3 videokamera i semiproff-klassen for å kunne lage film,
6898 samt sende live fra skoleteater/konserter. Vi har kjøpt inn digitale
6899 kompaktkamera til alle klassene. Vi har et team av lærere som skal i
6900 gang med å teste ut tablets på svake elever. Håpet et at teknologien
6901 kan være med på å gi noen av elevene litt mer motivasjon. Vi har kjøpt
6902 inn et halvt klassesett med pulsklokker, noe som har vist seg å være
6903 overraskende inspirerende for en del av elevene. Vi har også oss på
6904 fag på en høyskole litt lengre sør for oss, slik at
3 av oss nå skal
6905 ta faget
"Linux tjenestedrift
". Som inspektør og en del av skolens
6906 administrasjon er det veldig praktisk å kunne trå til hvis det
6907 kniper. Men IKT-ansvarlig har vært UTROLIG flink til å lage rene
6908 smørbrødlister for hvordan de mest vanlige driftsproblem løses, så det
6909 er lett for flere av oss å ta del i den daglige driften. Vi har svært
6910 stor nytte av lærling (som også hjelper to av naboskolene), men det er
6911 nesten blitt slik at det er om å gjøre å komme til først for å få løse
6912 problem. Det å få fingrene på problem og utfordringer er den aller
6913 beste læremester.

6927 bytte ut en av serverne våre, og da vil denne trolig bli satt opp som
6928 testserver for neste versjon av Skolelinux. På den måten vil vi i alle
6929 fall kunne gi tilbakemeldinger og rapportere feil. I tillegg så vil

6958 perhaps inspire others to test hardware as well. To test, I PXE

6961 something fail, I make a note about this in the test matrix and move
6962 on. If I have some spare time I try to report the bug to the OS
6963 vendor, but as I only have the machines for a short time, I rarely

7063 <description><p
>In the latest issue of Linux Journal, the readers choices were
7064 presented, and the winner among the multimedia player were VLC.
7065 Personally, I like VLC, and it is my player of choice when I first try
7066 to play a video file or stream. Only if VLC fail will I drag out
7067 gmplayer to see if it can do better. The reason is mostly the failure
7068 model and trust. When VLC fail, it normally pop up a error message
7069 reporting the problem. When mplayer fail, it normally segfault or
7070 just hangs. The latter failure mode drain my trust in the program.
<p
>
7072 <p
>But even if VLC is my player of choice, we have choosen to use
7073 mplayer in
<a href=
"http://www.skolelinux.org/
">Debian
7074 Edu/Skolelinux
</a
>. The reason is simple. We need a good browser
7075 plugin to play web videos seamlessly, and the VLC browser plugin is
7076 not very good. For example, it lack in-line control buttons, so there
7077 is no way for the user to pause the video. Also, when I
7078 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">last
7079 tested the browser plugins
</a
> available in Debian, the VLC plugin
7080 failed on several video pages where mplayer based plugins worked. If
7081 the browser plugin for VLC was as good as the gecko-mediaplayer
7082 package (which uses mplayer), we would switch.
</P
>
7084 <p
>While VLC is a good player, its user interface is slightly
7085 annoying. The most annoying feature is its inconsistent use of
7086 keyboard shortcuts. When the player is in full screen mode, its
7087 shortcuts are different from when it is playing the video in a window.
7088 For example, space only work as pause when in full screen mode. I
7089 wish it had consisten shortcuts and that space also would work when in
7090 window mode. Another nice shortcut in gmplayer is [enter] to restart
7091 the current video. It is very nice when playing short videos from the
7092 web and want to restart it when new people arrive to have a look at
7093 what is going on.

7560 migration. It uses qemu-img from the qemu package to make the disk
7561 image, parted to partition it, losetup and kpartx to present the disk
7562 image partions as devices, and dd to copy the data. I NFS mounted the
7563 new servers storage area on the old server to do the migration.

7862 TB zfs volume we currently use to store DV video. Because of this, I
7863 finally got around to do a test installation of Debian/Squeeze with
7864 kfreebsd. Installation went fairly smooth, thought I noticed some
7865 visual glitches in the cdebconf dialogs (black cursor left on the
7866 screen at random locations). Have not gotten very far with the
7867 testing. Noticed cfdisk did not work, but fdisk did so it was not a
7868 fatal problem. Have to spend some more time on it to see if it is
7869 useful as a file server for NUUG. Will try to find time to set up a
7870 gnash buildbot slave on the Debian Edu/Skolelinux this weekend.

>Prioritising packages for the Debian Edu /

"http://www.skolelinux.org/
">Skolelinux
</a
> DVD, which is
7881 supposed provide a school with all the services and user applications
7882 needed on the pupils computer network has always been hard. Even
7883 schools without Internet connections should be able to get Debian Edu
7884 working using this DVD.
</p
>
7886 <p
>The job became a lot harder when apt and aptitude started
7887 installing recommended packages by default. We want the same set of
7888 packages to be installed when using the DVD and the netinst CD, and
7889 that means all recommended packages need to be on the DVD. I created
7890 a patch for debian-cd in
<a href=
"http://bugs.debian.org/
601203">BTS
7891 report #
601203</a
> to do this, and since this change was applied to
7892 the Debian Edu DVD build, we have been seriously short on space.
</p
>
7894 <p
>A few days ago we decided to drop blender, wxmaxima and kicad from
7895 the default installation to save space on the DVD, believing that
7896 those needing these applications are few and can get them from the
7897 Debian archive.
</p
>
7899 <p
>Yesterday, I had a look what source packages to see which packages
7900 were using most space. A few large packages are well know;
7901 openoffice.org, openclipart and fluid-soundfont. But I also
7902 discovered that lilypond used
106 MiB and fglrx-driver used
53 MiB.
7903 The lilypond package is pulled in as a dependency for rosegarden, and
7904 when looking a bit closer I discovered that
99 MiB of the
106 MiB were
7905 the documentation package, which is recommended by the binary package.
7906 I decided to drop this documentation package from our DVD, as most of
7907 our users will use the GUI front-ends and do not need the lilypond
7908 documentation. Similarly, I dropped the non-free fglrx-driver package
7909 which might be installed by d-i when its hardware is detected, as the
7910 free X driver should work.
</p
>
7912 <p
>With this change, we finally got space for the LXDE and Gnome
7913 desktop packages as well as the language specific packages making the
7914 DVD more useful again.

>My
<a href=

</a

7926 raise money for the project is going well. The lower limit of
10
7927 signers was reached in
24 hours, and so far
13 people have signed it.
7928 More signers and more funding is most welcome, and I am really curious
7929 how far we can get before the time limit of December
24 is reached.
7932 <p
>On the #gnash IRC channel on irc.freenode.net, I was just tipped
7933 about what appear to be a great code coverage tool capable of
7934 generating code coverage stats without any changes to the source code.

7938 It is missing in Debian, but the git source built just fine in Squeeze
7939 after I installed libelf-dev, libdwarf-dev, pkg-config and
7940 libglib2.0-dev. Failed to build in Lenny, but suspect that is
7941 solvable. I hope kcov make it into Debian soon.

7948 release. Give it a try if you need a complete linux solution for your
7949 school, including central infrastructure server, workstations, thin
7950 client servers and diskless workstations. A nice touch added
7951 yesterday is RDP support on the thin client servers, for windows
7952 clients to get a Linux desktop on request.

7963 second most popular used package that is missing in Debian. The sixth
7964 most popular is flashplayer-mozilla. This is a clear indication that
7965 working flash is important for Debian users. Around
10 percent of the
7966 users submitting data to popcon.debian.org have this package
7967 installed.

7973 schools experienced with
<a href=
"http://www.skolelinux.org/
">Debian
7974 Edu/Skolelinux
</a
> was the lack of working Flash. A lot of educational
7975 web sites require Flash to work, and lacking working Flash support in
7976 the web browser and the problems with installing it was perceived as a
7977 good reason to stay with Windows.
</p

7979 <p
>I once saw a funny and sad comment in a web forum, where Linux was
7980 said to be the retarded cousin that did not really understand
7981 everything you told him but could work fairly well. This was a
7982 comment regarding the problems Linux have with proprietary formats and
7983 non-standard web pages, and is sad because it exposes a fairly common
7984 understanding of whose fault it is if web pages that only work in for
7985 example Internet Explorer
6 fail to work on Firefox, and funny because
7986 it explain very well how annoying it is for users when Linux
7987 distributions do not work with the documents they receive or the web
7988 pages they want to visit.
</p
>
7990 <p
>This is part of the reason why I believe it is important for Debian
7991 and Debian Edu to have a well working Flash implementation in the
7992 distribution, to get at least popular sites as Youtube and Google
7993 Video to working out of the box. For Squeeze, Debian have the chance
7994 to include the latest version of Gnash that will make this happen, as
7995 the new release
0.8.8 was published a few weeks ago and is resting in
7996 unstable. The new version work with more sites that version
0.8.7.
7997 The Gnash maintainers have asked for a freeze exception, but the
7998 release team have not had time to reply to it yet. I hope they agree
7999 with me that Flash is important for the Debian desktop users, and thus
8000 accept the new package into Squeeze.

8174 <description><p
>As reported earlier, the last few days I have looked at how Debian
8175 Edu clients are configured, and tried to get rid of all hardcoded
8176 configuration settings on the clients. I believe the work to be
8177 mostly done, and the clients seem to work just fine with dynamically
8178 generated configuration.
</p
>
8180 <p
>What is the point, you might ask? The point is to allow a Debian
8181 Edu desktop to integrate into an existing network infrastructure
8182 without any manual configuration.
</p
>
8184 <p
>This is what happens when installing a Debian Edu client here at
8185 the University of Oslo using PXE. With the PXE installation, I am
8186 asked for language (Norwegian Bokmål), locality (Norway) and keyboard
8187 layout (no-latin1), Debian Edu profile (Roaming Workstation), if I
8188 accept to reformat the hard drive (yes), if I want to submit info to
8189 popcon.debian.org (no) and root password (secret). After answering
8190 these questions, the installer goes ahead and does its thing, and
8191 after around
50 minutes it is done. I press enter to finish the
8192 installation, and the machine reboots into KDE. When the machine is
8193 ready and kdm asks for login information, I enter my university
8194 username and password, am told by kdm that a local home directory has
8195 been created and that I must log in again, and finally log in with the
8196 same username and password to the KDE
4.4 desktop. At no point during
8197 this process did it ask for university specific settings, and all the
8198 required configuration was dynamically detected using information
8199 fetched via DHCP and DNS. The roaming workstation is now ready for
8202 <p
>How was this done, you might wonder? First of all, here is the
8203 list of things that need to be configured on the client to get it
8204 working properly out of the box:
</p
>
8207 <li
>IP address/netmask and DNS server.
</li
>
8208 <li
>Web proxy URL.
</li
>
8209 <li
>LDAP server for NSS directory information (user, group, etc).
</li
>
8210 <li
>Kerberos server for PAM password checking.
</li
>
8211 <li
>SMB mount point to access the network home directory. (*)
</li
>
8212 <li
>Central syslog server to send syslog messages to. (*)
</li
>
8213 <li
>Sitesummary collector URL to submit info to central server. (*)
</li
>
8216 <p
>(Hm, did I forget anything? Let me knew if I did.)
</p
>
8218 <p
>The points marked (*) are not required to be able to use the
8219 machine, but needed to provide central storage and allowing system
8220 administrators to track their machines. Since yesterday, everything
8221 but the sitesummary collector URL is dynamically discovered at boot
8222 and installation time in the svn version of Debian Edu.
</p
>
8224 <p
>The IP and DNS setup is fetched during boot using DHCP as usual.
8225 When a DHCP update arrives, the proxy setup is updated by looking for
8226 http://wpat/wpad.dat and using the content of this WPAD file to
8227 configure the http and ftp proxy in /etc/environment and
8228 /etc/apt/apt.conf. I decided to update the proxy setup using a DHCP
8229 hook to ensure that the client stops using the Debian Edu proxy when
8230 it is moved outside the Debian Edu network, and instead uses any local
8231 proxy present on the new network when it moves around.
</p
>
8233 <p
>The DNS names of the LDAP, Kerberos and syslog server and related
8234 configuration are generated using DNS information at boot. First the
8235 installer looks for a host named ldap in the current DNS domain. If
8236 not found, it looks for _ldap._tcp SRV records in DNS instead. If an
8237 LDAP server is found, its root DSE entry is requested and the
8238 attributes namingContexts and defaultNamingContext are used to
8239 determine which LDAP base to use for NSS. If there are several
8240 namingContexts attibutes and the defaultNamingContext is present, that
8241 LDAP subtree is used as the base. If defaultNamingContext is missing,
8242 the subtrees listed as namingContexts are searched in sequence for any
8243 object with class posixAccount or posixGroup, and the first one with
8244 such an object is used as the LDAP base. For Kerberos, a similar
8245 search is done by first looking for a host named kerberos, and then
8246 for the _kerberos._tcp SRV record. I
've been unable to find a way to
8247 look up the Kerberos realm, so for this the upper case string of the
8248 current DNS domain is used.
</p
>
8250 <p
>For the syslog server, the hosts syslog and loghost are searched
8251 for, and the _syslog._udp SRV record is consulted if no such host is
8252 found. This algorithm works for both Debian Edu and the University of
8253 Oslo. A similar strategy would work for locating the sitesummary
8254 server, but have not been implemented yet. I decided to fetch and
8255 save these settings during installation, to make sure moving to a
8256 different network does not change the set of users being allowed to
8257 log in nor the passwords required to log in. Usernames and passwords
8258 will be cached by sssd when the user logs in on the Debian Edu
8259 network, and will not change as the laptop move around. For a
8260 non-roaming machine, there is no caching, but given that it is
8261 supposed to stay in place it should not matter much. Perhaps we
8262 should switch those to use sssd too?
</p
>
8264 <p
>The user
's SMB mount point for the network home directory is
8265 located when the user logs in for the first time. The LDAP server is
8266 consulted to look for the user
's LDAP object and the sambaHomePath
8267 attribute is used if found. If it isn
't found, the home directory
8268 path fetched from NSS is used instead. Assuming the path is of the
8269 form /site/server/directory/username, the second part is looked up in
8270 DNS and used to generate a SMB URL of the form
8271 smb://server.domain/username. This algorithm works for both Debian
8272 edu and the University of Oslo. Perhaps there are better attributes
8273 to use or a better algorithm that works for more sites, but this will
8274 do for now. :)
</p
>
8276 <p
>This work should make it easier to integrate the Debian Edu clients
8277 into any LDAP/Kerberos infrastructure, and make the current setup even
8278 more flexible than before. I suspect it will also work for thin
8279 client servers, allowing one to easily set up LTSP and hook it into a
8280 existing network infrastructure, but I have not had time to test this
8283 <p
>If you want to help out with implementing these things for Debian
8284 Edu, please contact us on debian-edu@lists.debian.org.
</p
>
8286 <p
>Update
2010-
08-
09: Simon Farnsworth gave me a heads-up on how to
8287 detect Kerberos realm from DNS, by looking for _kerberos TXT entries
8288 before falling back to the upper case DNS domain name. Will have to
8289 implement it for Debian Edu. :)

8298 <description><p
>A few years ago, I was involved in a project planning to use
8299 Windows file servers as home directory servers for Debian
8300 Edu/Skolelinux machines. This was thought to be no problem, as the
8301 access would be through the SMB network file system protocol, and we
8302 knew other sites used SMB with unix and samba as the file server to
8303 mount home directories without any problems. But, after months of
8304 struggling, we had to conclude that our goal was impossible.
</p
>
8306 <p
>The reason is simply that while SMB can be used for home
8307 directories when the file server is Samba running on Unix, this only
8308 work because of Samba have some extensions and the fact that the
8309 underlying file system is a unix file system. When using a Windows
8310 file server, the underlying file system do not have POSIX semantics,
8311 and several programs will fail if the users home directory where they
8312 want to store their configuration lack POSIX semantics.
</p
>
8314 <p
>As part of this work, I wrote a small C program I want to share
8315 with you all, to replicate a few of the problematic applications (like
8316 OpenOffice.org and GCompris) and see if the file system was working as
8317 it should. If you find yourself in spooky file system land, it might

>A few days ago, I
8530 <a href=
"http://people.skolelinux.org/pere/blog/Debian_Edu_roaming_workstation___at_the_university_of_Oslo.html
">tried
8531 to install
</a
> a Roaming workation profile from Debian Edu/Squeeze
8532 while on the university network here at the University of Oslo, and
8533 noticed how much had to change to get it operational using the
8534 university infrastructure. It was fairly easy, but it occured to me
8535 that Debian Edu would improve a lot if I could get the client to
8536 connect without any changes at all, and thus let the client configure
8537 itself during installation and first boot to use the infrastructure
8538 around it. Now I am a huge step further along that road.
</p
>
8540 <p
>With our current squeeze-test packages, I can select the roaming
8541 workstation profile and get a working laptop connecting to the
8542 university LDAP server for user and group and our active directory
8543 servers for Kerberos authentication. All this without any
8544 configuration at all during installation. My users home directory got
8545 a bookmark in the KDE menu to mount it via SMB, with the correct URL.
8546 In short, openldap and sssd is correctly configured. In addition to
8547 this, the client look for http://wpad/wpad.dat to configure a web
8548 proxy, and when it fail to find it no proxy settings are stored in
8549 /etc/environment and /etc/apt/apt.conf. Iceweasel and KDE is
8550 configured to look for the same wpad configuration and also do not use
8551 a proxy when at the university network. If the machine is moved to a
8552 network with such wpad setup, it would automatically use it when DHCP
8553 gave it a IP address.
</p
>
8555 <p
>The LDAP server is located using DNS, by first looking for the DNS
8556 entry ldap.$domain. If this do not exist, it look for the
8557 _ldap._tcp.$domain SRV records and use the first one as the LDAP
8558 server. Next, it connects to the LDAP server and search all
8559 namingContexts entries for posixAccount or posixGroup objects, and
8560 pick the first one as the LDAP base. For Kerberos, a similar
8561 algorithm is used to locate the LDAP server, and the realm is the
8562 uppercase version of $domain.
</p
>
8564 <p
>So, what is not working, you might ask. SMB mounting my home
8565 directory do not work. No idea why, but suspected the incorrect
8566 Kerberos settings in /etc/krb5.conf and /etc/samba/smb.conf might be
8567 the cause. These are not properly configured during installation, and
8568 had to be hand-edited to get the correct Kerberos realm and server,
8569 but SMB mounting still do not work. :(
</p
>
8571 <p
>With this automatic configuration in place, I expect a Debian Edu
8572 roaming profile installation would be able to automatically detect and
8573 connect to any site using LDAP and Kerberos for NSS directory and PAM
8574 authentication. It should also work out of the box in a Active
8575 Directory environment providing posixAccount and posixGroup objects
8576 with UID and GID values.

8588 <description><p
>The new roaming workstation profile in Debian Edu/Squeeze is fairly
8589 similar to the laptop setup am I working on using Ubuntu for the
8590 University of Oslo, and just for the heck of it, I tested today how
8591 hard it would be to integrate that profile into the university
8592 infrastructure. In this case, it is the university LDAP server,
8593 Active Directory Kerberos server and SMB mounting from the Netapp file
8596 <p
>I was pleasantly surprised that the only three files needed to be
8597 changed (/etc/sssd/sssd.conf, /etc/ldap.conf and
8598 /etc/mklocaluser.d/
20-debian-edu-config) and one file had to be added
8599 (/usr/share/perl5/Debian/Edu_Local.pm), to get the client working.
8600 Most of the changes were to get the client to use the university LDAP
8601 for NSS and Kerberos server for PAM, but one was to change a hard
8602 coded DNS domain name in the mklocaluser hook from .intern to
8605 <p
>This testing was so encouraging, that I went ahead and adjusted the
8606 Debian Edu scripts and setup in subversion to centralise the roaming
8607 workstation setup a bit more and avoid the hardcoded DNS domain name,
8608 so that when I test this tomorrow, I expect to get away with modifying
8609 only /etc/sssd/sssd.conf and /etc/ldap.conf to get it to use the
8610 university servers.
</p
>
8612 <p
>My goal is to get the clients to have no hardcoded settings and
8613 fetch all their initial setup during installation and first boot, to
8614 allow them to be inserted also into environments where the default
8615 setup in Debian Edu has been changed or as with the university, where
8616 the environment is different but provides the protocols Debian Edu

>The last few months me and the other Debian Edu developers have
8746 been working hard to get the Debian/Squeeze based version of Debian
8747 Edu/Skolelinux into shape. This future version will use Kerberos for
8748 authentication, and services are slowly migrated to single signon,
8749 getting rid of password questions one at the time.
</p
>
8751 <p
>It will also feature a roaming workstation profile with local home
8752 directory, for laptops that are only some times on the Skolelinux
8753 network, and for this profile a shortcut is created in Gnome and KDE
8754 to gain access to the users home directory on the file server. This
8755 shortcut uses SMB at the moment, and yesterday I had time to test if
8756 SMB mounting had started working in KDE after we added the cifs-utils
8757 package. I was pleasantly surprised how well it worked.
</p
>
8759 <p
>Thanks to the recent changes to our samba configuration to get it
8760 to use Kerberos for authentication, there were no question about user
8761 password when mounting the SMB volume. A simple click on the shortcut
8762 in the KDE menu, and a window with the home directory popped
8765 <p
>One step closer to a single signon solution out of the box in
8766 Debian Edu. We already had PAM, LDAP, IMAP and SMTP in place, and now
8767 also Samba. Next step is Cups and hopefully also NFS.

8769 <p
>We had planned a alpha0 release of Debian Edu for today, but thanks
8770 to the autobuilder administrators for some architectures being slow to
8771 sign packages, we are still missing the fixed LTSP package we need for
8772 the release. It was uploaded three days ago with urgency=high, and if
8773 it had entered testing yesterday we would have been able to test it in
8774 time for a alpha0 release today. As the binaries for ia64 and powerpc
8775 still not uploaded to the Debian archive, we need to delay the alpha
8776 release another day.

8796 <p
>As a step to try to see if it possible to merge the DNS and DHCP
8797 LDAP objects, I have had a look at how the packages pdns-backend-ldap
8798 and dhcp3-server-ldap in Debian use the LDAP server. The two
8799 implementations are quite different in how they use LDAP.
</p

8801 To get this information, I started slapd with debugging enabled and
8802 dumped the debug output to a file to get the LDAP searches performed
8803 on a Debian Edu main-server. Here is a summary.

8811 <p
>PowerDNS have two modes of operation using LDAP as its backend.
8812 One
"strict
" mode where the forward and reverse DNS lookups are done
8813 using the same LDAP objects, and a
"tree
" mode where the forward and
8814 reverse entries are in two different subtrees in LDAP with a structure
8815 based on the DNS names, as in tjener.intern and
8816 2.2.0.10.in-addr.arpa.
</p
>
8818 <p
>In tree mode, the server is set up to use a LDAP subtree as its
8819 base, and uses a
"base
" scoped search for the DNS name by adding
8820 "dc=tjener,dc=intern,
" to the base with a filter for
8821 "(associateddomain=tjener.intern)
" for the forward entry and

" with a filter for
8823 "(associateddomain=

" for the reverse entry. For
8824 forward entries, it is looking for attributes named dnsttl, arecord,

9034 The object classes need to have fixed names, and the configuration
9035 need to be stored in a fairly specific LDAP structure. On the
9036 positive side, the invidiual dhcpHost entires can be anywhere without
9037 the DN pointed to by the dhcpServer entries. The latter should make
9038 it possible to group all host entries in a subtree next to the
9039 configuration entries, and this subtree can also be shared with the
9040 DNS server if the schema proposed above is combined with the dhcpHost
9041 structural object class.

9045 <p

9046 to which LDAP schemas to use. While its

9051 <p

9053 I guess one could implement ones own schema, as long as the
9054 objectclasses and attributes have the names used, but this do not
9055 really help when the DHCP subtree need to have a fairly fixed
9056 structure.

>For a while now, I have wanted to find a way to change the DNS and
9108 DHCP services in Debian Edu to use the same LDAP objects for a given
9109 computer, to avoid the possibility of having a inconsistent state for
9110 a computer in LDAP (as in DHCP but no DNS entry or the other way
9111 around) and make it easier to add computers to LDAP.

've looked at how powerdns and dhcpd is using LDAP, and using this
9114 information finally found a solution that seem to work.
</p

9116 <p
>The old setup required three LDAP objects for a given computer.
9117 One forward DNS entry, one reverse DNS entry and one DHCP entry. If
9118 we switch powerdns to use its strict LDAP method (ldap-method=strict
9119 in pdns-debian-edu.conf), the forward and reverse DNS entries are
9120 merged into one while making it impossible to transfer the reverse map
9121 to a slave DNS server.
</p
>
9123 <p
>If we also replace the object class used to get the DNS related
9124 attributes to one allowing these attributes to be combined with the
9125 dhcphost object class, we can merge the DNS and DHCP entries into one.
9126 I
've written such object class in the dnsdomainaux.schema file (need
9127 proper OIDs, but that is a minor issue), and tested the setup. It
9128 seem to work.
</p
>
9130 <p
>With this test setup in place, we can get away with one LDAP object
9131 for both DNS and DHCP, and even the LTSP configuration I suggested in
9132 an earlier email. The combined LDAP object will look something like

9153 <p

9154 dhcphost in a different location, to allow us to put the objects
9155 outside the

9156 that. If I can

9376 <description><p
>For a laptop, centralized user directories and password checking is
9377 a bit troubling. Laptops are typically used also when not connected
9378 to the network, and it is vital for a user to be able to log in or
9379 unlock the screen saver also when a central server is unavailable.
9380 This is possible by caching passwords and directory information (user
9381 and group attributes) locally, and the packages to do so are available
9382 in Debian. Here follow two recipes to set this up in Debian/Squeeze.
9383 It is also possible to set up in Debian/Lenny, but require more manual
9384 setup there because pam-auth-update is missing in Lenny.
</p
>
9386 <h2
>LDAP/Kerberos + nscd + libpam-ccreds + libpam-mklocaluser/pam_mkhomedir
</h2
>
9388 This is the traditional method with a twist. The password caching is
9389 provided by libpam-ccreds (version
10-
4 or later is needed on
9390 Squeeze), and the directory caching is done by nscd. The directory
9391 lookup and password checking is done using LDAP. If one want to use
9392 Kerberos for password checking the libpam-ldapd package can be
9393 replaced with libpam-krb5 or libpam-heimdal. If one is happy having a
9394 local home directory with the path listed in LDAP, one can use the
9395 pam_mkhomedir module from pam-modules to make this happen instead of
9396 using libpam-mklocaluser. A setup for pam-auth-update to enable
9397 pam_mkhomedir will have to be written until a fix for
9398 <a href=
"http://bugs.debian.org/
568577">bug #
568577</a
> is in the
9399 archive. Because I believe it is a bad idea to have local home
9400 directories using misleading paths like /site/server/partition/, I
9401 prefer to create a local user with the home directory in /home/. This
9402 is done using the libpam-mklocaluser package.

've been unable to get TLS
9414 certificate checking for a self signed certificate working, which make
9415 LDAP authentication unsafe for Debian Edu (nslcd is not checking if it
9416 is talking to the correct LDAP server), and very much welcome feedback

>The last few days I have been looking into the status of the LDAP
9583 directory in Debian Edu, and in the process I started to miss a GUI

9585 Debian/Squeeze and Lenny is
9586 <a href=
"http://luma.sourceforge.net/

9587 be a great tool to get a overview of the current LDAP directory
9588 populated by default in Skolelinux. Thanks to it, I have been able to
9589 find empty and obsolete subtrees, misplaced objects and duplicate
9590 objects. It will be installed by default in Debian/Squeeze. If you
9591 are working with LDAP, give it a go. :)
</p

9593 <p
>I did notice one problem with it I have not had time to report to
9594 the BTS yet. There is no .desktop file in the package, so the tool do
9595 not show up in the Gnome and KDE menus, but only deep down in in the
9596 Debian submenu in KDE. I hope that can be fixed before Squeeze is
9599 <p
>I have not yet been able to get it to modify the tree yet. I would
9600 like to move objects and remove subtrees directly in the GUI, but have
9601 not found a way to do that with LUMA yet. So in the mean time, I use
9602 <a href=

9609 useful GUI alternative. It seem like a good tool, but is unmaintained
9610 in Debian and got a RC bug keeping it out of Squeeze. Unless that
9611 changes, it will not be an option for Debian Edu based on Squeeze.

9621 <a href=
"http://people.skolelinux.org/pere/blog/Time_for_new__LDAP_schemas_replacing_RFC_2307_.html
">complained
9622 about the fact
</a

9623 for storing DNS and DHCP information in LDAP to combine the two sets
9624 of information into one LDAP object representing a computer.
</p
>
9626 <p
>In the mean time, I discovered that a simple fix would be to make
9627 the dhcpHost object class auxiliary, to allow it to be combined with
9628 the dNSDomain object class, and thus forming one object for one
9629 computer when storing both DHCP and DNS information in LDAP.
</p
>
9631 <p
>If I understand this correctly, it is not safe to do this change
9632 without also changing the assigned number for the object class, and I
9633 do not know enough about LDAP schema design to do that properly for
9634 Debian Edu.

9672 of Debian upgrades

9673 finally made the upgrade logs available from

"http://people.skolelinux.org/pere/debian-upgrade-testing/
">http://people.skolelinux.org/pere/debian-upgrade-testing/
</a
>.
9675 I am now testing dist-upgrade of Gnome and KDE in a chroot using both
9676 apt and aptitude, and found their differences interesting. This time
9677 I will only focus on their removal plans.
</p
>
9679 <p
>After installing a Gnome desktop and the laptop task, apt-get wants
9680 to remove
72 packages when dist-upgrading from Lenny to Squeeze. The
9681 surprising part is that it want to remove xorg and all
9682 xserver-xorg-video* drivers. Clearly not a good choice, but I am not
9683 sure why. When asking aptitude to do the same, it want to remove
129
9684 packages, but most of them are library packages I suspect are no
9685 longer needed. Both of them want to remove bluetooth packages, which
9686 I do not know. Perhaps these bluetooth packages are obsolete?
</p
>
9688 <p
>For KDE, apt-get want to remove
82 packages, among them kdebase
9689 which seem like a bad idea and xorg the same way as with Gnome. Asking
9690 aptitude for the same, it wants to remove
192 packages, none which are
9691 too surprising.
</p
>
9693 <p
>I guess the removal of xorg during upgrades should be investigated
9694 and avoided, and perhaps others as well. Here are the complete list
9695 of planned removals. The complete logs is available from the URL
9696 above. Note if you want to repeat these tests, that the upgrade test
9697 for kde+apt-get hung in the tasksel setup because of dpkg asking
9698 conffile questions. No idea why. I worked around it by using
9699 '<tt

9846 <description><p
>The last few days I have done some upgrade testing in Debian, to
9847 see if the upgrade from Lenny to Squeeze will go smoothly. A few bugs
9848 have been discovered and reported in the process
9849 (
<a href=
"http://bugs.debian.org/
585410">#
585410</a
> in nagios3-cgi,
9850 <a href=
"http://bugs.debian.org/
584879">#
584879</a
> already fixed in
9851 enscript and
<a href=
"http://bugs.debian.org/
584861">#
584861</a
> in
9852 kdebase-workspace-data), and to get a more regular testing going on, I
9853 am working on a script to automate the test.
</p
>
9855 <p
>The idea is to create a Lenny chroot and use tasksel to install a
9856 Gnome or KDE desktop installation inside the chroot before upgrading
9857 it. To ensure no services are started in the chroot, a policy-rc.d
9858 script is inserted. To make sure tasksel believe it is to install a
9859 desktop on a laptop, the tasksel tests are replaced in the chroot
9860 (only acceptable because this is a throw-away chroot).
</p
>
9862 <p
>A naive upgrade from Lenny to Squeeze using aptitude dist-upgrade
9863 currently always fail because udev refuses to upgrade with the kernel
9864 in Lenny, so to avoid that problem the file /etc/udev/kernel-upgrade
9865 is created. The bug report
9866 <a href=
"http://bugs.debian.org/
566000">#
566000</a
> make me suspect
9867 this problem do not trigger in a chroot, but I touch the file anyway
9868 to make sure the upgrade go well. Testing on virtual and real
9869 hardware have failed me because of udev so far, and creating this file
9870 do the trick in such settings anyway. This is a
9871 <a href=
"http://www.linuxquestions.org/questions/debian-
26/failed-dist-upgrade-due-to-udev-config_sysfs_deprecated-nonsense-
804130/
">known
9872 issue
</a
> and the current udev behaviour is intended by the udev
9873 maintainer because he lack the resources to rewrite udev to keep
9874 working with old kernels or something like that. I really wish the
9875 udev upstream would keep udev backwards compatible, to avoid such
9876 upgrade problem, but given that they fail to do so, I guess
9877 documenting the way out of this mess is the best option we got for
9878 Debian Squeeze.
</p
>
9880 <p
>Anyway, back to the task at hand, testing upgrades. This test
9881 script, which I call
<tt

>Som systemarkitekten bak Skolelinux, kan jeg bare riste på hodet
10004 over påstanden om at Skolelinux krever desentraliserte tjenere.
10005 Skolelinux-arkitekturen er laget for sentralisert drift og plassering
10006 av tjenerne lokalt eller sentralt alt etter behov og nettkapasitet.
10007 Den er modellert på nettverks- og tjenerløsningen som brukes på
10008 Universitetet i Tromsø og Oslo, der jeg jobber med utvikling av
10009 driftstjenester. Dette er det heldigvis noen som har fått med seg, og
10010 jeg er glad for å kunne sitere fra en kommentar på den overnevnte
10011 artikkelen. Min venn og gamle kollega Sturle Sunde forteller der:
10014 <p
>I Flora kommune køyrer vi Skulelinux på skular med alt frå
15 til
10015 meir enn
500 elevar. Dei store skulane har eigen tenar, for det er
10016 mest praktisk. Eg, som er driftsansvarleg for heile nettet, ser
10017 sjeldan dei tenarane fysisk, men at dei står der gjer skulane mindre
10018 avhengige av eksterne linjer som er trege eller dyre. Dei minste
10019 skulane har ikkje eigen tenar. Å bruke sentral tenar er heller ikkje
10020 noko problem. Småskulane klarar seg fint med
1 mbit-linje til ein
10021 sentral tenar eller tenaren på ein større skule.
</p
>
10023 <p
>Det beste med Skulelinux er halvtjukke klientar. Dei treng ikkje
10024 harddisk og brukar minimalt med ressursar på tenaren fordi dei køyrer
10025 programma lokalt. Eit klasserom med
30 sju-åtte år gamle maskiner har
10026 mykje meir CPU og RAM totalt enn nokon moderne tenar til under
10027 millionen. Det trengst to kommandoar på den sentrale tenaren for å
10028 oppdatere alle klientane, både tynne og halvtjukke. Vi har ingen
10029 problem med diskar som ryk heller, som var eit problem før fordi
10030 elevane sat og sparka i maskinene. Og dei krev lite bandbreidde i
10031 nettet, so det er fullt mogleg å køyre slike på småskular med trege
10032 linjer mot tenaren på ein større skule.
</p
>
10034 <p
>Flora kommune har nesten
800 Linux-maskiner i sitt skulenett, og
10035 ein person som tek seg av drift av heile nettet, inkludert tenarar,
10036 klientar, operativsystem, programvare, heimekontorløysing og
10037 administrasjon av brukarar.

>After a long break from debian-installer development, I finally
10191 found time today to return to the project. Having to spend less time
10192 working dependency based boot in debian, as it is almost complete now,
10193 definitely helped freeing some time.
</p
>
10195 <p
>A while back, I ran into a problem while working on Debian Edu. We
10196 include some firmware packages on the Debian Edu CDs, those needed to
10197 get disk and network controllers working. Without having these
10198 firmware packages available during installation, it is impossible to
10199 install Debian Edu on the given machine, and because our target group
10200 are non-technical people, asking them to provide firmware packages on
10201 an external medium is a support pain. Initially, I expected it to be
10202 enough to include the firmware packages on the CD to get
10203 debian-installer to find and use them. This proved to be wrong.
10204 Next, I hoped it was enough to symlink the relevant firmware packages
10205 to some useful location on the CD (tried /cdrom/ and
10206 /cdrom/firmware/). This also proved to not work, and at this point I
10207 found time to look at the debian-installer code to figure out what was
10208 going to work.
</p
>
10210 <p
>The firmware loading code is in the hw-detect package, and a closer
10211 look revealed that it would only look for firmware packages outside
10212 the installation media, so the CD was never checked for firmware
10213 packages. It would only check USB sticks, floppies and other
10214 "external
" media devices. Today I changed it to also look in the
10215 /cdrom/firmware/ directory on the mounted CD or DVD, which should
10216 solve the problem I ran into with Debian edu. I also changed it to
10217 look in /firmware/, to make sure the installer also find firmware
10218 provided in the initrd when booting the installer via PXE, to allow us
10219 to provide the same feature in the PXE setup included in Debian
10222 <p
>To make sure firmware deb packages with a license questions are not
10223 activated without asking if the license is accepted, I extended
10224 hw-detect to look for preinst scripts in the firmware packages, and
10225 run these before activating the firmware during installation. The
10226 license question is asked using debconf in the preinst, so this should
10227 solve the issue for the firmware packages I have looked at so far.

10240 Edu finally entered the Debian archive. Today, the new
10241 <a href=

10247 passed NEW on Monday. In addition, the
10248 <a href=

">libpam-ccreds
</a
>
10249 package we need is in experimental (version
10-
4) since Saturday, and
10250 hopefully will be moved to unstable soon.
</p
>
10252 <p
>This collection of packages allow for two different setups for
10253 roaming laptops. The traditional setup would be using libpam-ccreds,
10254 nscd and libpam-mklocaluser with LDAP or Kerberos authentication,
10255 which should work out of the box if the configuration changes proposed
10256 for nscd in
<a href=
"http://bugs.debian.org/
485282">BTS report
10257 #
485282</a
> is implemented. The alternative setup is to use sssd with
10258 libpam-mklocaluser to connect to LDAP or Kerberos and let sssd take
10259 care of the caching of passwords and group information.
</p
>
10261 <p
>I have so far been unable to get sssd to work with the LDAP server
10262 at the University, but suspect the issue is some SSL/GnuTLS related
10263 problem with the server certificate. I plan to update the Debian
10264 package to version
1.2, which is scheduled for next week, and hope to
10265 find time to make sure the next release will include both the
10266 Debian/Ubuntu specific patches. Upstream is friendly and responsive,
10267 and I am sure we will find a good solution.
</p
>
10269 <p
>The idea is to set up the roaming laptops to authenticate using
10270 LDAP or Kerberos and create a local user with home directory in /home/
10271 when a usre in LDAP logs in via KDM or GDM for the first time, and
10272 cache the password for offline checking, as well as caching group
10273 memberhips and other relevant LDAP information. The
10274 libpam-mklocaluser package was created to make sure the local home
10275 directory is in /home/, instead of /site/server/directory/ which would
10276 be the home directory if pam_mkhomedir was used. To avoid confusion
10277 with support requests and configuration, we do not want local laptops
10278 to have users in a path that is used for the same users home directory
10279 on the home directory servers.
</p
>
10281 <p
>One annoying problem with gdm is that it do not show the PAM
10282 message passed to the user from libpam-mklocaluser when the local user
10283 is created. Instead gdm simply reject the login with some generic
10284 message. The message is shown in kdm, ssh and login, so I guess it is
10285 a bug in gdm. Have not investigated if there is some other message
10286 type that can be used instead to get gdm to also show the message.

10443 <description><p
>For some years now, I have wondered how we should handle laptops in
10444 Debian Edu. The Debian Edu infrastructure is mostly designed to
10445 handle stationary computers, and less suited for computers that come
10448 <p
>Now I finally believe I have an sensible idea on how to adjust
10449 Debian Edu for laptops, by introducing a new profile for them, for
10450 example called Roaming Workstations. Here are my thought on this.
10451 The setup would consist of the following:
</p
>
10455 <li
>During installation, the user name of the owner / primary user of
10456 the laptop is requested and a local home directory is set up for
10457 the user, with uid and gid information fetched from the LDAP
10458 server. This allow the user to work also when offline. The
10459 central home directory can be available in a subdirectory on
10460 request, for example mounted via CIFS. It could be mounted
10461 automatically when a user log in while on the Debian Edu network,
10462 and unmounted when the machine is taken away (network down,
10463 hibernate, etc), it can be set up to do automatic mounting on
10464 request (using autofs), or perhaps some GUI button on the desktop
10465 can be used to access it when needed. Perhaps it is enough to use
10466 the fish protocol in KDE?
</li
>
10468 <li
>Password checking is set up to use LDAP or Kerberos
10469 authentication when the machine is on the Debian Edu network, and
10470 to cache the password for offline checking when the machine unable
10471 to reach the LDAP or Kerberos server. This can be done using
10472 <a href=
"http://www.padl.com/OSS/pam_ccreds.html
">libpam-ccreds
</a
>
10473 or the Fedora developed
10474 <a href=
"https://fedoraproject.org/wiki/Features/SSSD
">System
10475 Security Services Daemon
</a
> packages.
</li
>
10477 <li
>File synchronisation with the central home directory is set up
10478 using a shared directory in both the local and the central home
10479 directory, using unison.
</li
>
10481 <li
>Printing should be set up to print to all printers broadcasting
10482 their existence on the local network, and should then work out of
10483 the box with CUPS. For sites needing accurate printer quotas, some
10484 system with Kerberos authentication or printing via ssh could be
10485 implemented.
</li
>
10487 <li
>For users that should have local root access to their laptop,
10488 sudo should be used to allow this to the local user.
</li
>
10490 <li
>It would be nice if user and group information from LDAP is
10491 cached on the client, but given that there are entries for the
10492 local user and primary group in /etc/, it should not be needed.
</li
>
10496 <p
>I believe all the pieces to implement this are in Debian/testing at
10497 the moment. If we work quickly, we should be able to get this ready
10498 in time for the Squeeze release to freeze. Some of the pieces need
10499 tweaking, like libpam-ccreds should get support for pam-auth-update
10500 (
<a href=
"http://bugs.debian.org/
566718">#
566718</a
>) and nslcd (or
10501 perhaps debian-edu-config) should get some integration code to stop
10502 its daemon when the LDAP server is unavailable to avoid long timeouts
10503 when disconnected from the net. If we get Kerberos enabled, we need
10504 to make sure we avoid long timeouts there too.

">Yesterdays
10517 NUUG presentation
</a
> about Kerberos was inspiring, and reminded me
10518 about the need to start using Kerberos in Skolelinux. Setting up a
10519 Kerberos server seem to be straight forward, and if we get this in
10520 place a long time before the Squeeze version of Debian freezes, we
10521 have a chance to migrate Skolelinux away from NFSv3 for the home
10522 directories, and over to an architecture where the infrastructure do
10523 not have to trust IP addresses and machines, and instead can trust
10524 users and cryptographic keys instead.
</p
>
10526 <p
>A challenge will be integration and administration. Is there a
10527 Kerberos implementation for Debian where one can control the
10528 administration access in Kerberos using LDAP groups? With it, the
10529 school administration will have to maintain access control using flat
10530 files on the main server, which give a huge potential for errors.
</p
>
10532 <p
>A related question I would like to know is how well Kerberos and
10533 pam-ccreds (offline password check) work together. Anyone know?
</p
>
10535 <p
>Next step will be to use Kerberos for access control in Lwat and
10536 Nagios. I have no idea how much work that will be to implement. We
10537 would also need to document how to integrate with Windows AD, as such
10538 shared network will require two Kerberos realms that need to cooperate
10539 to work properly.
</p
>
10541 <p
>I believe a good start would be to start using Kerberos on the
10542 skolelinux.no machines, and this way get ourselves experience with
10543 configuration and integration. A natural starting point would be
10544 setting up ldap.skolelinux.no as the Kerberos server, and migrate the
10545 rest of the machines from PAM via LDAP to PAM via Kerberos one at the
10548 <p
>If you would like to contribute to get this working in Skolelinux,
10549 I recommend you to see the video recording from yesterdays NUUG
10550 presentation, and start using Kerberos at home. The video show show
10551 up in a few days.

>6 years ago, as part of the Debian Edu development I am involved
10561 in, I asked for a hook in the kdm and gdm setup to run scripts as root
10562 when the user log out. A bug was submitted against the xfree86-common
10563 package in
2004 (
<a href=
"http://bugs.debian.org/
230422">#
230422</a

10564 and revisited every time Debian Edu was working on a new release.
10565 Today, this finally paid off.
</p
>
10567 <p
>The framework for this feature was today commited to the git
10568 repositry for the xorg package, and the git repository for xdm has
10569 been updated to use this framework. Next on my agenda is to make sure
10570 kdm and gdm also add code to use this framework.
</p
>
10572 <p
>In Debian Edu, we want to ability to run commands as root when the
10573 user log out, to get rid of runaway processes and do general cleanup
10574 after a user. With this framework in place, we finally can do that in
10575 a generic way that work with all display managers using this
10576 framework. My goal is to get all display managers in Debian use it,
10577 similar to how they use the Xsession.d framework today.

>One of the new features in the next Debian/Lenny based release of
10609 Debian Edu/Skolelinux, which is scheduled for release in the next few
10610 days, is automatic configuration of the service monitoring system
10611 Nagios. The previous release had automatic configuration of trend
10612 analysis using Munin, and this Lenny based release take that a step
10615 <p
>When installing a Debian Edu Main-server, it is automatically
10616 configured as a Munin and Nagios server. In addition, it is
10617 configured to be a server for the
10618 <a href=
"http://wiki.debian.org/DebianEdu/HowTo/SiteSummary
">SiteSummary
10619 system
</a
> I have written for use in Debian Edu. The SiteSummary
10620 system is inspired by a system used by the University of Oslo where I
10621 work. In short, the system provide a centralised collector of
10622 information about the computers on the network, and a client on each
10623 computer submitting information to this collector. This allow for
10624 automatic information on which packages are installed on each machine,
10625 which kernel the machines are using, what kind of configuration the
10626 packages got etc. This also allow us to automatically generate Munin
10627 and Nagios configuration.
</p
>
10629 <p
>All computers reporting to the sitesummary collector with the
10630 munin-node package installed is automatically enabled as a Munin
10631 client and graphs from the statistics collected from that machine show
10632 up automatically on http://www/munin/ on the Main-server.
</p
>
10634 <p
>All non-laptop computers reporting to the sitesummary collector are
10635 automatically monitored for network presence (ping and any network
10636 services detected). In addition, all computers (also laptops) with
10637 the nagios-nrpe-server package installed and configured the way
10638 sitesummary would configure it, are monitored for full disks, software
10639 raid status, swap free and other checks that need to run locally on
10640 the machine.
</p
>
10642 <p
>The result is that the administrator on a school using Debian Edu
10643 based on Lenny will be able to check the health of his installation
10644 with one look at the Nagios settings, without having to spend any time
10645 keeping the Nagios configuration up-to-date.
</p
>
10647 <p
>The only configuration one need to do to get Nagios up and running
10648 is to set the password used to get access via HTTP. The system
10649 administrator need to run
"<tt
>htpasswd /etc/nagios3/htpasswd.users
10650 nagiosadmin
</tt
>" to create a nagiosadmin user and set a password for
10651 it to be able to log into the Nagios web pages. After that,
10652 everything is taken care of.

10726 get to know the Skolelinux system. Walter Bender, involved in the

10728 also helped me improve my OLPC installation. He also showed me that
10729 his Turtle Art application can be used in standalone mode, and we
10730 agreed that I would help getting it packaged for Debian. As a
10731 standalone application it would be great for Debian Edu. We also
10732 tried to get the video conferencing working with two OLPCs, but that
10733 proved to be too hard for us. The application seem to need more work
10734 before it is ready for me. I look forward to getting home and relax

>The state of standardized LDAP schemas on Linux is far from
10745 optimal. There is RFC
2307 documenting one way to store NIS maps in
10746 LDAP, and a modified version of this normally called RFC
2307bis, with
10747 some modifications to be compatible with Active Directory. The RFC
10748 specification handle the content of a lot of system databases, but do
10749 not handle DNS zones and DHCP configuration.

10752 we would like to store information about users, SMB clients/hosts,
10753 filegroups, netgroups (users and hosts), DHCP and DNS configuration,
10754 and LTSP configuration in LDAP. These objects have a lot in common,
10755 but with the current LDAP schemas it is not possible to have one
10756 object per entity. For example, one need to have at least three LDAP
10757 objects for a given computer, one with the SMB related stuff, one with
10758 DNS information and another with DHCP information. The schemas
10759 provided for DNS and DHCP are impossible to combine into one LDAP
10760 object. In addition, it is impossible to implement quick queries for
10761 netgroup membership, because of the way NIS triples are implemented.
10762 It just do not scale. I believe it is time for a few RFC
10763 specifications to cleam up this mess.

10765 <p
>I would like to have one LDAP object representing each computer in
10766 the network, and this object can then keep the SMB (ie host key), DHCP
10767 (mac address/name) and DNS (name/IP address) settings in one place.
10768 It need to be efficently stored to make sure it scale well.

10805 <a href=
"http://no.speling.org/
">den norske stavekontrollen for bokmål
10806 og nynorsk
</a
> til å ikke bruke bindestrek som ordskillemarkør, lyktes jeg
10807 endelig første juledag. Bruken av bindestrek som ordskillemarkør har
10808 gjort det umulig å få med ord med bindestrek i
10809 stavekontrolldatagrunnlaget, slik at ord som e-post og CD-spiller ikke
10810 kunne godtas av stavekontrollen. Hadde litt tid til overs å bruke på
10811 stavekontrollen, og satte meg ned med to kopier av byggsystemet og en
10812 liten testdatafil, og byttet ut - med = på utvalgte steder i
10813 byggsystemet og datafilen helt til jeg fikk samme resultat med det
10814 gamle og det nye byggsystemet. Dette tror jeg var forsøk
4, der de
10815 foregående har feilet uten at jeg klarte å forstå hvorfor. Det sier
10816 kanskje litt om kompleksiteten i det originale byggsystemet som Rune
10817 Kleveland laget i sin tid.

10819 <p
>Etter å ha endret byggsystemet, var neste steg å importere ordene
10820 med bindestrek. Vi har en rekke slike i databasene for

10824 for korrektur av datagrunnlaget for stavekontrollen, og etter importen
10825 skulle nå
10350 nye ord bli godkjent som korrekt stavede ord av
10826 stavekontrollen.

>This weekend we had a small developer gathering for Debian Edu in
10836 Oslo. Most of Saturday was used for the general assemly for the
10837 member organization, but the rest of the weekend I used to tune the
10838 LTSP installation. LTSP now work out of the box on the
10-network.
10839 Acer Aspire One proved to be a very nice thin client, with both
10840 screen, mouse and keybard in a small box. Was working on getting the
10841 diskless workstation setup configured out of the box, but did not
10842 finish it before the weekend was up.

4 VGA cards in one box we got from
10845 the Brazilian group, so that will have to wait for the next
10846 development gathering. Would love to have the Debian Edu installer
10847 automatically detect and configure a multiseat setup when it find one
10848 of these cards.

>Recently I have spent some time evaluating the multimedia browser
10858 plugins available in Debian Lenny, to see which one we should use by
10859 default in Debian Edu. We need an embedded video playing plugin with
10860 control buttons to pause or stop the video, and capable of streaming
10861 all the multimedia content available on the web. The test results and
10862 notes are available on
10863 <a href=
"http://wiki.debian.org/DebianEdu/BrowserMultimedia
">the
10864 Debian wiki
</a
>. I was surprised how few of the plugins are able to
10865 fill this need. My personal video player favorite, VLC, has a really
10866 bad plugin which fail on a lot of the test pages. A lot of the MIME
10867 types I would expect to work with any free software player (like
10868 video/ogg), just do not work. And simple formats like the
10869 audio/x-mplegurl format (m3u playlists), just isn
't supported by the
10870 totem and vlc plugins. I hope the situation will improve soon. No
10871 wonder sites use the proprietary Adobe flash to play video.
